I didn't notice it had this rear in it until it was on the rollback and really didn't think to look because I've never seen one in person, I guess the same po installed the traction bars and massive shackles Those are leaving with the rear as soon as monsoon season is over.

I thought you had to change the ends of the axle tubes when changing from a tapered/keyed axle to the 65 and later flanged style? Kevin

Kevin Anyone that raced the old stuff with the tappered axles got rid of them... when I raced my 62 out on Woodward YEARS ago I had a pile of keys in the glove box.. if it hooked good they sheared off... I finally put a newer B-body 8 3/4 in it

In my case the easiest and cheapest solution was to narrow a Dana 60, buy new 30 spline axles, use Mopar ends and 10" brakes. If you build a lighter car and don't abuse it a 8&3/4 will last just fine. 1986 Dodge Ramcharger 440 2wd, Bracket Racer Under Construction 1998 Ram 2500 QuadCab, new daily driver. 2008 Honda Element 2014 Carry-On 7x14 Cargo Trailer

I'm just looking to get the car on the road as easy as possible, so hopefully I can just drop this center out and put in my later housing. I have housings but only this center to use.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

Not so far other then it being stripped out to start building a drag car. Luckly he kept and labeled all the interior pieces. This is a numbers car minus the rearend, but whats weird is it has a flat mount k member in it

I took a 1964 B body rear end housing and had it cut down one inch narrower than a stock A body 8 3/4 for my 1971 Duster I bought the newer axle bearing ends from Summit and bought a set of Strange Engr. 35 spline axles and spool for it I didn't have a back brace installed on it It ended up bending really bad Last edited by Cab_Burge; 05/20/13 12:47 PM.

No 1-piece OEM axle will fit, but I make a reasonably priced custom length axle package that will. You must change the brakes and inner axle seals, but the original housing ends can remain intact.

Another question, do I need adjustable axle bearings or not? I bought a set of a body axles from Dr. Diff for my valiant and I don't think they were adjustable, atleast if they were they haven't been adjusted lol. These axles going in my later b body housing do have an adjuster. Can I just get a set of plain bearings without it?
