I just installed the electric wiper motor in my 58 Suburban to replace the factory vacuum wipers.
Unfortunately, I can't remember if I got it from LMC Truck. I live in Kansas City and can easily drive to LMC, Jim Carters and Classic Chevy Truck Parts. I've been shopping at all three. I pickep up the wiper motor about 4 months ago and just can't remember where I got it.
Anyway, all the being said it was the easiest thing I've done on my truck so far. Once I removed the "huge" factory radio to get access to the wipers it was a piece of cake. Old one dropped right out, new one bolted right in. Works like a charm. The kit I bought came with all the required hardware and included a switch. I looked on the LMC website at the part. It looks like what I bought and the price looks right.
I've noticed that you seem to see the same stuff sold at a lot of the parts houses. I would assume that the same kit is sold at all three that I've visited.
Bottom line is I bought something very similar, if not the same, and it was an easy install and works great. I'd feel confident picking up the LMC unit.
