I run a N/O/P Mopar
@ 3500 to 3700 Lbs.
I would strong recommend to 8 3/4
The 8 1/4 is had to find gears for and
really much weaker!

Even in the Mid 70's Larry Shepard at the Mopar
Performance Seminars strong recommended losing
the 8 1/4
He stated that Mopar save a little over a single dollar
when they replaced the 8 3/4 with the 8 1/4. I guess
every dollar counted with a Mfg. that was bleeding money
at that time!
