Pacesetter header clearance problems?

[8879ford]

Anyone else have any problems installing pacesetter headers? I installed a set of the ceramic coated headers on my 88 bronco II 4x4, 2.9...on the drivers side the header came in contact with the fuel filter sheild thingy...To get it installed, i had to put a spacer between the motor and the motor mount to gain the clearance. I thought this was a odd problem, but the guys at pacesetter said they have never heard of this problem.

They fit on my 91 explorer without rubbing on anything. But I wouldn't say they fit like a glove. The angles where the headers meet the Y just didn't quite line up like they should have.
