Does anyone know what the difference between the early 93 exhaust manifolds (which fit 91-93) and the late 93 exhaust manifolds (which fit 93-96) are? I'm looking at the pics at Rock Auto and they look identical to me. I have a late 93 by the manifold dates (after 4/5/93 is considered late, mine is 5/93) and I know they added the EGR for 94 MTs, but I don't have one so it can't be that.

The late 93 right is an ATP brand (thus the different image style) and the rest are Dormans. The different gasket style on the late 93 right is interesting even though Felpro uses the same style gasket for 91-95 and then a different style starting in 96, not sure why it would change over like that if the same manifolds were used.

Any thoughts?
