55mm mass and 60mm throttle body...I believe just the 86 had the 58mm TB and 87-93 had 60mm TB`s.

55mm mass and 60mm throttle body...I believe just the 86 had the 58mm TB and 87-93 had 60mm TB`s.

I was pretty sure there is a difference between the 58mm and the 60mm.

I have this big technical reference Mustang book and it says just the 1986,5.0L stangs had a 58mm TB and the 87-93 models were all 60mm with the exception of the 93 Cobra that came with a 65mm TB.
Stock mass air meter is 55mm.93 Cobra mass air meter is 70mm.
