Chrysler 8.75 for Aspen/Volare

[Paul can elaborate for himself but imagine he’s just stating that since the OP is going to run a stocker he’ll need to run a racing wheel which offers different offsets so he’ll just have to measure what will work. BTW a 10 inch wheel is what’s needed.]
That's understandable, but what I said, he has to use-make a housing with the same width, backing plate to backing plate as original (rule book) then find a rim that will work. In other words If that 8-1/4 is 53" the 8-3/4 has to be 53" so find whatever, cut it to the right size, unless NHRA is not checking that anymore.?

5.13 gear is what we run unless going to Denver......

We ran (carefully) Mirada for a long time (Now belongs to Bakersfield
Track Manager who won class at a Nationals this year with the old Girl)
with a very expensive/trick 8 1/4 Paul Rossi built.
It held up well.....But we kept our fingers crossed !

BTW it is still in the car to this day and racing. Again = Gears
past 4.50 are no longer available and that is not enough gear
for a 3500 lb. plus 318 Stocker to be very competitive.

i just want to be clear with your statement. When you say gears above 4.5, you are talking about the 8 14"

Correct David: It is the 8 1/4 that is ratio challenged,,,,, I get
less clear every year and often confuse myself too!

Larry Shepherd said at a Seminar in mid 70s that Mopar saved
around a dollar when the went to a 8 1/4 over a 8 3/4.

Thanks to everyone for their input, I have my eye on a complete 8 3/4 rear end on Craigslist. Have a great Thanksgiving weekend, Craig.
