Upper and lower control arms ...interchangeable?

Aloha all, I wanted to ask you all a very specific 1979 Camaro front end suspension question, let me explain my dilemma. I own a 1955 Chevy truck that has a issue with how the front clip of a 1979 Camaro was welded up to the 1955 truck chassis. The front tire is about 2 inches off- center up front. Meaning I need to move the front hub forward 2" and was hoping since it seems like the upper and lower control arms from 1970-1981 will fit the 1979 chassis, maybe if I install the upper and lower control arms from either the 1970-73 or 1980-1981, they may move my front hub forward between 2-3"...I wanted an easy way to achieve this rather than having a shop cut and weld the entire front end just for a few inches...I guess every inch counts!
Any info be great.

No, you are just asking for more trouble by messing around with control arms etc. Can the whole subframe be moved ahead by the two inches ? I am wondering if they did this that way so they could use the stock driveshaft or something ? It sounds like it is time to do it right by starting over !

Agree, apparently, the subframe ws not squared before attachment.
People used 2nd Gen subframes because of having disc brakes and front steering allowing use of most any oil pan.

Re: Upper and lower control arms ...interchangeable?

Even if you had custom A arms made to do what you want, the steering linkage geometry would be off & the coil springs would not line up. Itís far easier to cut the sub off & relocate it.

Check my web page for First Gen Camaro suspension info:

Thanks for the posts, yes on all points. It does look like the subframe was connected to keep everything aligned from the transmission mounts, engine mounts and steering box as well as the way the radiator sits on the chassis. All looks solidly done, accept for the 2" off center for the front hub, I guess they had there reasons...its a bit of an eye sore but it does ride and drive well. Wanted to stay at about the 15" wheel size, but I was thinking maybe 18" wheels all the way around would close this gap...well, I will post a few pics, after I figure out how to shrink the size of my photos...thanks again everyone, I will be back for some Wilwood brake or other brake upgrade options.
