So is there a size difference in engine compartments of 1967-1972 and 1973-1976 A-bodies? Still wondering if there are an benefits of using either car, even if it's just an inch difference in room.
‘67-‘76 A body engine bays are all the same size, the center link, idler, and pitman arms varied over model years and sometimes causes clearance issues. ‘63-‘66 engine bays are smaller and ‘60-‘62 engine bays even smaller (marginal)
I hope this helps.
Motor mounts are also their own along the years ‘73 was the last change until A bodies were discontinued.
