3.1 intake changes?

Hey everyone-

 

Does anybody know if there were intake changes made on the 3.1 MPFI between 1990 and 1991? I've got a great deal on some gaskets that fit a 1991 3.1, but the guy keeps telling me that they will not fit a 1990 3.1. Is this true? Or bullshit......

Thanks!

Yeah, 90 used a paper plenum gasket and different plenum bolts. 91+ uses metal plenum gaskets with different plenum bolts. Go to Advance and ask for a set from a 90 and a 91 and compare them

hmmmm.......so i guess it wouldn't even be possible for me to fit a 91 gasket onto a 90 3.1? Or are they just different materials that would otherwise match up?
