Chevy Express/GMC Savana Accessories & Modifications

Hello, Someone ask about adding seats to their van.
I added three bench seats to my Express cargo van by getting the tracks, seat belt winders, and seats from an older Savana van and installing them in my Express cargo van.
It worked out really well. I can now haul 11 people!
I can tell more about it, If someone is planning to do this.

    I have a 2000 Express with 184K miles. I am installing a beefed up transmission for heavier towing capacity and I'd like to know if a 3/4 ton differential would be a "bolt in" fit. I know it'll be the next thing to go, I'd just like to be ready when it does. I'd also be interested in any mods to the existing rear axle to make it more reliable.


  • I have 2001 Express LT, love it, hate the mirrors vibrating.
    A turkey vulture actually ripped off the entire passenger side mirror, I thought, I'll just replace them with the new and improved heated with turn signals version, I believe 03-06.
    Based on your experience, what are your comments on these mirrors?
  • Well I did install the new updated mirror, ran two wires from the right and left front turn signals, so I have the blinkers working fine, however wiring the movement and heat for the new mirror to the van's wiring has proved to be a major problem without having a wiring diagram. Does anyone have a 2001 Express 1500 and a 2006 mirror wiring charts?
  • Bill, I am adding a bench seat to my 8 passenger Express passenger van. I am about to do the drilling through the floor board. Did you have any problem and was there a exhaust shield in your way? If you read this post this month (August 2006) I would appreciate your input. :)

    where are you located ?
    I added a bench to my 1500. worked out fine.
  • I finally got the seat in with help from a friend who is a Gunsmith. He had all the correct tools and the seat was installed in less than 2 hours. The one problem I still have is the after-market seat belts do not look the same as the seat belts that are factor. The after market belts do not bolt in the same either. I am trying to figure how to get them in or if I should just e-bay the belt and go buy OEM belts that should bolt in perfectly without any question.

    Did you have any issues with installing seat belts or did you have belts that were GM? I got all my seat belts for $114 and I know if I buy belts that are GM it could cost $100 each.

    I installed GM belts, which I bought from a place in california
    van's great
  • I got my seat and After-market belts from the same shop. I only had the choice to buy after market belts for the 2001 Express. I am sounding like a broken record but the retractor part of the belt is not for my year and I either have to go to a salvage yard to get a part of a later year Express to mount the retractor of the belt or go buy some OEM belts from a Chevy/GMC dealer.

    Did your retractor and belts look exactly like the rest of the stock seat belts that were in your van? with no plastic around the retractor and two seperate belt clips to attach the belt on both sides of the seat? On my after market belt it attaches to the seat by bolts on one side and a standard belt clip only at the end of the belt. Below is how my after market belt looks like: image

    The challenge that I am having is how to mount the retractor part of the seat belt on the back wall. I bought some factor bolt from a GMC dealer so that I would have the correct bolts (right strength and size) but I do not see how I am going to fit this retractor on the back wall of the van. Any suggestions.
  • Hi Bill,
    I recently bought a 1995 Chevy G30 cargo van. I need to put in a bench seat but don't know where to bolt it down to. I don't want to just bolt it to the sheet metal, because I don't want it to tear out in the event of an accident. It seems like the main frame beams are U shaped. Any suggestions?

    Did you have any luck with adding the 3rd row bench? I want to add one as well. Can you add just a short track extension or do you have to install a new tracks? Any advice would be great!!

    Hi Brett, I only added one bench seat up behind the driver's seat, but what I ended up doing is finding a used bench that had brackets on the bottom that were spaced the same as the main frame beams. These brackets were just simple plates with holes in them. I put 8 inch long, ½ inch thick bolts all the way through the frame and used some wide washers on either end. Seems to be working well.

    I wish to install the LT captain chairs in my AWD Express, but have not been able to determine if they will fit my bench seat floor brackets. If so, I will try to find tan seats in a salvage yard. John
  • I just read your post. I have an 06 GMC 2500 Cargo van. It has manual mirrors and I want to install electric mirrors. Any ideas if this is possible. I have heard that the wiring harness should already be inside the door, Also would I have to replace the entire mirror or just the inside parts.

  • I too interested in replacing my mirror with the oem blinking mirrors. do you have the part number for them? my dealer is no help in 'researching' the part for me. thanks
  • For those with newer Express (mine is an '07) and have power mirror and heated mirror, the existing harness already has the wirings for the mirror blinker. All you have to do is purchase a set of oem blinker mirrors from the dealer and swap them out. No additional wire or mod is necessary. Easiest job!
  • hi, bill!

    i have a 2009 chevy express cargo 1500. What's the best way to install a rear seat for 3. i sure do want to leave ample space in the middle. i was thinking maybe installing it close to the end. can i get some advice in installing the seat securely? thanks.

    I have wanted to install 4 bucket seats (from '01-02 LT model?? did not get any help re 'are the brackets similar?' in my 03 AWD passenger van. Instead, I installed a '4th row set of brackets and belts, with the existing 3x seats'. Everybody was reluctant to do the work, re the weight capacity, safety - insurance liability. This is the only way I can carry plywood, etc. without removing the @#$%^non-folding +headrest, seats. I do like the seat in the most rear position - limo style! Otherwise, the main option is fixed base seats from an upfitter or van accessory store. It is incredible, GM never had the forsight to offer a 'crew version' of the cargo van. (They will never do it now!) Otherwise, the AWD van is a super, incredible vehicle, blows the doors off a pickup/suburban, for my needs.

    I am interested in buying a 1500 AWD van and need additional seats if I do so. How easy is it to install 3 or 4 more seats in the rear? What are the weight considerations? I have 5 children all 11 and under. Thanks for you insight...

    The 'safety issue' is the major problem - who will do the work! The school bus vans flipping has terrified the market. Stabilitrak, standard on passenger vans, is not offered on cargo and conversion models. Installing the extra row of floor rails and belts is not, otherwise, difficult.
