tubular control arm question

[mrdana60]

Ok I m working on a 72 1/2 ton and I bought some uppers and lower tubular control arms. The uppers has cpp paperwork with them.
installed the uppers and was just fine. Installed the lowers and they did not match up with the coil spring cups on the engine crossmember. I had them on the right side. Thought I may have had them backwards but I didnt. Any idea on what might be the cause? I know pics would help. Thanks and hope everyone has a great weekend.
