12 Bolt vs 10 Bolt Rear - Page 4

MR DERBY CITY · 04-22-2018, 09:09 PM

If Dan runs K SA and if I have figured his combo correctly at 299 HP the total weight including driver is 4055 lbs. I sure hope that 8.5 is as durable as a 12 bolt.

Been talking with Moser, Mark Williams and Strange

They do not make a C Clip Eliminator Kit and Axles for a 10 Bolt and with Disk Brakes..
They do not have a 12 bolt that bolts in

Looks like everything has to be fabricated to make it work.

Anyone have an idea how to get past this??

One other questions.
Can you use a G-Body Rear on a B-Body?

My experience is that weight is what kills a rearend.
I moved to a lighter class and the rearend problems stopped,I probably have 100 more hp today than I had when I was breaking gears but no sign of cracking nowadays.
Most abused 12 bolt I've seen is from a 283 Impala (stick)

69 Nova 350/255/280. 3250# in G/SA. 3390# in H/SA. 8.5" 10-bolt rear. Broke a couple teeth off 1 set of gears in 7 years. Strange c-clip eliminators, 33 spline axles, spool, richmond gears. Your results may vary.

Oh have options.
But not one for my Axle using a Disk Brake.

You could always change the axle ends. It wouldn't hurt to weld the axle tubes to the center too.

Yeah..
Got a special case here.
Moser, Strange and MW do not specialize on B-Bodys.

Right now a new with good parts will cost $5000, Damn !

One asked if a G-Body 8.5 rear would fit.

look at the Police 91C rears they generally came with disc brakes---or as somebody said cut the ends off and put 12 bolt ends on it--google what you are trying to do others have put G body rears into a B body just have to rework the arms and move the brake hose/shock holes etc. to match what you have
