65 C20 to C10 changeover - The 1947 - Present Chevrolet & GMC Truck Message Board Network

So as far as parts, are the upper control arms the same? Will the shaft for the lower control arm fit in the C10 arm, or is it larger also? Seems like I can swap the upper control arm ball joint, but maybe not?
Finding pics for this stuff has been tough, so any info you guys have on the c10/c20 differences will help a lot!

Here's something I was just wondering, is the actual crossmember different between c10/c20?

I do not know if the C20 LCA shaft will fit a C10 LCA. I've never tried it......no reason to. Yes the crossmember is different as I stated before. There are no saddles to accept a round LCA shaft. I have a pic of a '63-'66 C20 LCA but it is apparently on my other computer.

Not a problem, I am going to just find a donor. I have a few emails out to CL ads. I was trying to avoid having to pull the stock crossmember and hoist the engine, but looks like that is the best bet. Going to work on the rear half first then tackle the front.

Thank you for your help!

Like others have said, no need to hoist the motor.

Post#4 shows some poor photography of my truck when I did my swap. Assuming you have the original bellhousing crossmember with a transmission hanging off the back, you'll be fine
