I have a V6 in my front 85 housing and it fits just fine. I'm running 5.29's (not that the gear ratio should matter I think) and it fits. How long did you try and slid it in? If I remember right its pretty much just the pinion thats stronger. The ring gear is still an 8" ring gear but just a tad thicker.
yea mines 5.29d too. i tried for a while. it really seems as though because the ring gear is thicker that it is getting hung up
