Brake conversion. Lower control arm swap?
Make sure to check the new cam bolts against the old ones.
It was awhile ago, but there were some that weren’t threaded far enough down the bolt so the washer and nut would bottom out before the bushing was squeezed down. So the alignment wouldn’t hold. And then if you do something like torque the ever-living-crap out of the bolt, rather than investigating what’s actually wrong, you can have a bolt failure. Wasn’t me, but it definitely happened.
Good practice anyway, not all the reproduction stuff matches the originals and it can cause issues.
