Reworking an 8 1/4 and can't find ?

I upgraded my '75 8.25 from 2.45 open to 3.55 SG.
I got ALOT of help from 69Mope. :prayer:
What a wealth of information.
I procured one from a '92 Dakota 2wd.
Went in like a champ and works like a dream.
Maybe ping him up.
Also, got good info from DR. Diff. :prayer:
