You’d have to move both upper and lower, I’d think, to keep the same geometry…and I’ve only looked at a 94 impalaIs the lower ball joint moved? Could be a problem, or even an improvement.

Depends on what you're gonna use the truck for....mine is a toy.Even if the Impala arms fit, should they be used on the GMT400... do they have the strength?

Would have to see comparison pictures. Like what was stated above for a street truck they would probably be just fine. Impalas or the caprice sedans were heavy cars and were even rated to tow decent weights compared to modern cars. May need to notch your a-arm mounting brackets to get it aligned. I may be surprised but I doubt the UCA and LCA mounting geometry is the same between the two vehicles.Even if the Impala arms fit, should they be used on the GMT400... do they have the strength?
Hats off to you for trying and experimenting with these parts.
Smiley's Racing sells all the parts to make your own upper control arm from adjustable pieces. This is my Sunbeam Alpine crossmember mocked up with Mustang II parts on the driver's side. Six years later and it's still sitting in pieces on the shop floor...I've been doing some research on Mustang II suspension lately. SPEC makes an UCA where both arms are a turnbuckle. I dunno, might be useful to make an upper and lower that way so you can get everything exactly where you want it and then make a jig from that so that build your own control arms.
