Thanks for all the info on the Cobra and TBird IRS units. I'm trying to find out if anyone has any info/pics on the IRS units used in the later model Explorer vehicles. One of the members (OLDGUY I think) posted pictures of the center section. The housing looks much stronger than the Cobra housing. The hub carriers may be similar to the 427 Cobra hub carrier. The units may be less expensive than the Cobra. I think the axles (at least the inners) are 31 spline. Does anyone know about the brakes and wheel bolt pattern?
Thanks again.
