Will this rear end fit?

B BODY
'64 = 60 7/8" (Exc.Max Wedge)
'68-'70= 60 1/8"

drum to drum measurements. It is a little long on the width.. you will have to relocate the spring perches for a OE fit, and adjust rear wheel backspacing to fit properly in your wheel well.

It IS close enough to get it to fit and work, it just wont be perfect. Because of that.. expect rear shackle bushings to wear quicker, tire clearance issues, and front leaf eyelet bushing wear issues. May have to address pinion angle most likely.
 
Ahh... So basically everything on each side would need moved 3/8"? How big of a deal would it be if ya didn't move them? As long as there wasn't any clearance problems.
Cheapest 8 3/4 rear i've seen, Just wonder if it's still cheaper if i'd have to move everything...
 
You may want to save your cash for a little stronger 489 case that was actually a bit stronger -especially the axles -but its your car

Thanks didn't know that, figured 8 3/4 were all the same... I would like something strong for when i build a stroker. I just know this 8 1/4 won't hold up to my abuse :p
 
Nice looking rear haha, That doesn't sound like a bad deal. I did a search for 489 and found a case for sale would that swap in place of the 741 in the fury rear? but i guess that still wouldn't do anything about the stronger axle like you were talking about?
Thanks for the link i'll finish it in the morning.
 
I've never actually worked on one, but isn't a 8 3/4 rear end from 64 the kind that has the hubs and brake drums that are held on with a big nut and need a puller of some sort to remove? If so, I don't think your 8 1/4 brakes will work, but I could be wrong.

If it were me, I would look for the later (65-73 or 74, I think) 8 3/4 axle housing with the brake drums that just slide over the studs on the axle, and then make sure it was the right width.
 
I have the stock 64 rear in my Belvedere and it is the type with the big nuts on the ends.Save your money and look for the newer style 68-70.Mine is going bye bye as soon ss i get the new one together.
 
Nick,

You are going in the opposite direction of the '64 and older guys - LOL. A lot of us have ditched the tapered axle rearends for later model 8 3/4s. I put a '68 GTX rear in my '64 Belvedere. The spring perches are the same, but the '64 B body rearend is the widest of them all, so you would lose a little tire clearance. I think I picked up an inch or so between the 2 sides. The 741 is plenty strong unless you're putting some serious hp in front of it. Remember, Hemis were using 741 rears in '64, and Max Wedges before that.

The tapered axle rear is a fine rearend, but it is little more work to pull the axles - you need a special puller. If you have the tool, no big deal. If you don't, it's a hassle.

I have the same rear end in my '64 Fury, and it's always been a pain. Getting the drums off has always been hell, even with the proper tools. An old joke (perhaps not so much of a joke) was to loosen the nuts and drive the car around a bunch of curves to loosen the drums. This axle also has the smallest 8-3/4 pinion shaft, and tapered axles. It is almost always swapped out by builders (and is my eventual plan). No doubt that is why the one you found is on sale!
 
Alright thanks guys, Glad i asked you guys i figured it would of been the samething as a newer one. I'll look for something better.

The 41 case has the smallest pinion shaft but have never seen a broken one.....and if you do, it'll be broken right behind the splines at the first shoulder which are the pretty much the same as on the others. So, this weak vs strong/small vs large 8 3/4 pinion doesn't really hold water. In all the years I've been playing with this stuff, I've only heard of one person that broke a shaft but I have shaved a few teeth off of them....small and large alike.

totally agree. its not the pinion that fails in most cases, but either the gear teeth or carrier main caps.
