This isn't really a racing question, but not really a mustang question either. My dad and I are thinking about building a T-Bucket. I found a great place for a kit, but they wany large amounts of money for things I think we can find elsewhere. One of these things is a rear end. The kit includes an 8" housing, which measures 51.25" flange-to-flange. Can I have a set of stock 28-spline axles out of a mustang 8" shortened and resplined to fit this? Or am I stuck with aftermarket pieces? The car would have a 302/C4 in it, and be very light, so I would think stock axles would handle it no problem. Any suggestions?

By the way, I posted a general question in the Exotic Fords section to see if anyone has built one of these. There's a link to the kit site, too.

28 spline axles are tapered; you cannot shorten them

51.25 is about an inch shorter overall than a '65-'66 Mustang housing... I wonder why the oddball length, especially for an 8"?

I think that's stock early Falcon.

I don't know if this is true or not, but I've been told 28 spline 8" axles will fit into a 9" housing/pumpkin?
Making the assumption the 28 spline axles are the same between the 8 and 9, I'm pretty sure they can be shortened and resplined (a machinist at work shortened a set for his Ranger). I think Currie Enterprises used to do this, too.

Yes 8" 28 spline and 9" 28 spline are the same and some axles will interchange but not all are the same axle used in different applications so check very close if you try it, if you can find an old set of axles that have no taper they can be shortened and resplined but most 28s are reduced to smaller than the splined area so when shortened a bit cannot be resplined, if you shorten them about a foot the diameter will be back up to the splined size so they'll work. Personally I'd buy the Currie's and save the hunting, bent and twisted hassles .
