lower A-arm interchange - The 1947 - Present Chevrolet & GMC Truck Message Board Network

68 TT · 03-13-2010, 12:02 PM

I need a set of 3/4-ton lower A-arms for my C2500 disc brake swap but there are no C20 or C30 trucks in the wrecking yard around here at the moment.

There are a few G30 vans that share the lower ball joint with the C20 & C30 but the interchange book says the A-arms are different.

Anybody know what is different about the van lower A-arms that make the interchange book say they won't work on a truck?

If there were any 2-wd trucks in the wrecking yard I would tear some off a van and see if they fit the truck but there are none to be found at the moment.

Any help would be greatly appreciated.
