Talk to Coventry West in Atlanta, I've heard they are considered the best place to get a diff rebuilt.

I didn't go there simply because if the expense and hassle of cross border shipping 2 ways to send in my core to be rebuilt. Shipping would cost more than the rebuilding. Shipping is cheap within the USA, it goes crazy expensive when borders are crossed. Last time I bought a differential from Welsh in Ohio it was an NOS X300 diff; the freight was close to $800, and I cleared customs myself. They were helpful and looked into various shipping options but that was the best either of us could do.

 

Same splines and 7/16 holes on the Chrysler application?

Usually I see the Ford and early Jeep applications when
I search by spline configuration. That's how I ended up
with an Auburn Suregrip.

 

That I don't know. The axle splines are different on Chrysler, 30 vs 19 for Jaguar, I don't know about the pinion splines. The "guts" of the Powr Lok were the same. I wasn't looking for a crown wheel and pinion, so didn't look at the Chrysler bolting.

44lawrence; the shop was called in 1994 "Gary's driveline" dont know if they are still there,or same people.

i think they were on State avenue, Holly hill fla.

 

.

plums i had an 1982 Camaro, it had the weak rear end, 305 dog engine.

when i upgraded to a 467" BBC, GM 400 trans. it lasted about 2 blocks.

so at that time 1988 i bought from Chevrolet hi-performance a complete rear assembly housing Dana 44 diff. with race disc brakes. it was for road race cars!

when i dissasembled it it had the Auburn LSD, with the 8.5" ring gear.

never any problems at all!

never

if you are using a 4L80E transmission , along with a 2.88 rear ratio, your final ratio in over drive would be YIKES, 2.16-1 that almost just 2 to 1.

acceleration would be slow, unless you have plenty of torque, and Jag V12 dont have much torque,(in my opinon).

i suppose MPG would fair well as long as engine is not lugging to maintain hyway speeds,(like always working to maintain, with throttle open more than requiered. fuel MPG would decrease.

 

1973 Firebird Trans Am

Pretty sure the stock 10 bolt had a cone type as well.

Again no problems and capable of blasting past snow plows
in a Vermont blizzard on Firestone F60-15 belted summers

That car never had snows and was very capable and controllable
in any slippery conditions. Very smooth takeup without drama.

 

I am running a 4L80E and 6 Litre in my 1989 XJRS with 2.88 diff. No problem with acceleration and cruising at our speed limits of 100/110Kph is effortless at just under 1900 RPM. No lugging and average fuel consumption of 10.4 litres per 100 km.

 

if it works for you ,so be it!

but i can gaurentee that my 1978 V12 ,5.3, with the 3.73 ratio would blast past you on acceleration, and i can cruise effortlessly at 75/80mph. 130mph in overdrive is just about 5000rpm, and it will still pull more,but who the heck is going to drive that fast on a daily base?

and V12s are never gonna break a fuel mileage test!

can your car do this,pic, HEY just having fun!!.LOL.

 

As you say it's different strokes but all fun.
As for pic, no l don't think mine would do that but then again over here they crush cars for "loss of traction"
