Camaro subframe bushing issue

[bowt1ed]

Alright guys - I know this has been beat to death in the past, but I ran into a speed bump and must query the group... Finally started putting new bushings in my control arms (1980 Camaro) after powder coating and (only) the upper rears aren't fitting. The 424's are suppose to measure 1 5/16", my old ones measure the same. However, both new 424's actually measure 1 7/16". Has anyone else run into this, and if so, what # bushing did you go to? Thanks.

Cheers, Jim
