I've got an early TPI unit ('86 by the casting numbers) that I want to put on my '91 RS. I know about the manifold bolt angles, but what concerns me is that the '91 RS (TBI) has a brace coming off of the AC compressor going to the manifold. Does the later TPI intake have a place for this brace, or is there a special "TPI AC Compressor Brace" that I'll have to find.

Anybody that has turned an LO3 into an LB9 could probably help me.

Any other surprises (fuel lines, etc) besides the standard stuff (covered in the TBI to TPI article)?

Thanks.
