Hello Mark. Thanks for the reply. Didn't plan on the Ocala show. This rear end is wider than an a body 8 3/4 at 52 5/8. The fender lips on my dart have been rolled in. Probably a result of the rear end width and the 10" rear rims and street radials. The 2:45 gear probably killed the build with the car sitting years and the owner passing away. The bolt pattern is 4.5 x 5. After getting the car back together and driving around the block I realized the housing limit 2:75 gear was a no go. Maybe in an automatic the 2:45 gear will be ok but in a 4 spd from a dead stop the disc won't last long from slipping it to get the car moving. But if your going to the bonneville salt flats, this is the one. The gears looked fine and the gear oil was normal dirty. As for the bearings I can't say as I literally idled around the block in first gear. Thanks.
