Can anyone tell me the flange to flange width of the rear axle for a 63/64 Riviera?


Thanks

Hey Ed,
I can get a drum to drum pretty easily since I have the frame off the car. Would that work?

Dave, that would be great. If you'll measure from mounting surface to mounting surface on the faces of the drums, that would be the exact measurement I need.

Thanks,

Ed

Ed,
58 11/16's is your number

50 7/16 back of drum edge to drum edge. Each drum is 4 1/8 to mounting face,

Is this cool?

Dave,

That's great news - perfiect numbers. I've found a Ford 8.8" posi with a 3.73 gear, and disc brakes. It's out of a Ford Explorer. It's much lighter weight, the 3.73 is a nice gear to go with the .67 overdrive of the 200R4, (w/ overdrive, I'll have a final drive of 2.49 which translates to about 2100 rpm's at 70 mph w/ 235/50/18 tires) The Ford rear is 59" flange to flange. I think the wheel houses in the '64 can handle an additional 5/16" especially if I divide it in two, it's only 5/32" on each side.

I just bought a complete set of Scarebird brackets for the front (locally off Craigslist for less than half of retail; never mounted and they're still in the original packaging.) Bobby Ward at North Yale auto has a '76 riv with all the other brake stuff I'll need - booster, master cylinder, lines, proportioning valve, and calipers. Now I'll just need to have the Riv brackets welded to the Ford rear. Wah Lah, four wheel discs.

Think we could make weld on bracket kits for those wanting different axles? I'm simularly going to change rear axles but probably to GM 8.5in 10-bolt out of a 90's B-body.
