iron duke exhaust manifold?

well, i've posted in the 'wanted' forum with no luck. also checked out all the vendors here. again, no luck. same with craig's list and even e*bay. does anyone know of a place where i can get a replacement exhaust manifold for a 1981 cj5 2.5L pontiac iron duke?
i know i can swap most of the engine parts with the 120/140 GM marine engines, but the exhaust manifold won't... at least till i get my snorkel on!
thanks for any help here.

I thought the later GM 2.5's used in the S-10 were the same as the earlier 2.5's used in the Jeeps and Chevy Citation. This manifold is for an 87 S-10 4x2. ,

i've checked those out and they are not the same. at least that's what all the parts store guys tell me. and the pics of them do look different as well. the change came in about 1983 or '84 for those engines. i think it was that GM dropped the individual make engines. no more pontiac, oldsmobile, buick, cadillac specific engines. they all shared the same GM engines after that.

i dont remember any stock ones when i still had mine but i think cliffor performance had a set of headers. It was basically just the left bank of their chevy V-8... Really dont remember my reference info but i just remember thier name being an option,... dont think it was very cheap either....give them a call...

mine already has the DT headers. they won't clear the steering and shifter linkage (3 on-the-tree) in the 1966 cj5a i'm swapping the 2.5 into. i did finally find a stock exhaust manifold that was in really nice shape. thanks all.
