what posi would fit in the stock rearend of a 66

Re: posi:)
 

Need to know what Diferential you have there. like 10 bolt , 12 bolt, what gears you have in there. Then we can possibly help. I just did install an Eaton posi in a 12 bolt with 373 gears. ....

Re: posi:)
 

Larry, what did that posi run ya?

Re: posi:)
 

12 bolt 3.73

Re: posi:)
 

Power Train is where I checked first 372 dollars. Need to add shipping and carrier bearings to tha price. They were slow to get it to me so i went to Reider Racing. All said and done with new carrier bearings included.
2nd day delivery around 4 bills 1+800 -770-0524 - Tony is who sent the order.

Re: posi:)
 

Got one Eaton from Reider Racing pn 12/P4S is what will work for a 12....373 ratio........Power Trax has some good units too. I just happen to prefer sticking to the Eatons.

Re: posi:)
 

well i think im going to go to my local speed shop and pick it up so its an eaton part #12/p4s and i will get the posi kit and new carrier barrings?

Re: posi:)
 

my 64 was factory posi.

Re: posi:)
 

I think I may have overpaid for my posi. Picked it up from a guy that looks like he frequents the pick-n-pulls a couple times, daily.
12 Bolt Posi with 373' with 6 lug drums in place setup for coils with the track bar = $550

Let the beatings begin...

Re: posi:)
 

How did that work for you Larry? I bought the Eaton Posi unit with 3:73 Richmond Ring & Pinion, Moser axels and all the bearings, shims, and goodies needed to finish the install. Do you like the feel of it going down the road?

Re: posi:)
 

ok, i'll start... I just found a 12 bolt 6 lug 3.73 w/posi 2WD coil rear at the local yard, came from a 69/70....

paid $35 (+$10 for the torch) I have to admit that was a lucky find. Noticed the truck, opened the glove box and my jaw dropped...had a 6 banger too but not sure what engine it was...
