If you're interested in porting the stock Eaton, let me know. Pete, Rick and I can help you do the install in no time. We did an article about Posi Performance for Motorhead magazine and swapped out 2-3 blowers that day. Its even easier if you could "borrow" a spare Eaton from someone to send out for porting so you don't have to disable the car all that time while it's out.
I'm pretty sure Rick still has my spare one?
