Default Front suspension differences?

Hi,guys-my first post here. Can anyone tell me the actual dimensional differences between the early and later front C4 control arms? I'm building a tube chassis car and bought individual parts as they became available,unaware that there had been a change. I think I may have mis-matched upper and lower control arms. Any help anyone could give me would be greatly appreciated.

Some of the serious racers on this board know this stuff in detail. I am pretty sure nothing is mix and match between the early and late C4's. pick up points, even wheel offsets are different.
But...what are you working on?

Sorry-I guess I should have given a little more info. It's a 65 Nova I'm doing a tube frame for. I did a triangulated 4 link in the rear and C4 in the front. Like I said,I bought ebay parts as they became available but I didn't realize until after I had everything that there had been a change from early to later years. I think the upper arms are too long,when I hang the pieces on the chassis the spindle is tilted quite a bit. I'll run through my pick-up points measurements again but I think I have mis-matched control arms.
I honestly don't remember specifically what years the pieces I bought were advertised as,I just thought "Oh,yeah-that's a C4 control arm" and hit the BIN button.
I'm at work right now so I don't have access to my Photobucket account,I'll throw some pics up later on.
Thanks for the responses-

Peter

This should be a pretty good deal;
