1990 Silverado Wiper Problem

I have a wiper problem and have narrowed it down to the pulse module. My problem is the pulse module in my truck is an older rectangular model, not the 'C' shaped one that is readily available at stores and on the net.
Does anyone know how to obtain or repair this older model pulse module?

Thanks.
