Posi

This is a 1974 N Case, 31 spline, 4 pin, 3:50 geared posi / limited slip. This is a used drop out.The gears will work, but they are rust pitted. No cracks or chips in teeth, front pinion seal was dry when removed from F100/150. Can send pics of gear teeth via email if you like. Run as is if you like. I need $600 for this unit, plus shipping USA. Because shipping is so expensive, (Jan 1st they increased rates), I will cover anything over $100 in MOST cases. Thanks.


New price...$600 plus shipping.

Here's an all new 31 spline posi unit, with new 3:50 gear ratio gears, 10 used posi bolts with washers, and a used 3L50 limited slip id tag. The bearings were put on the new unit were very low miles in excellent shape. Great stuff to put in your 9 center section, and your yoke would be correct. $400 plus shipping USA.

These items are still for sale MINUS the bolts...I needed them. I would sell gears separate from the posi unit if wanted, and the tag would go with the gears. The bundle is now $325 plus shipping.

More 2 sell

Hi peoples...I'm back. I have decided to sell the next two 9"posi units I have AS IS, meaning I will still inspect them carefully, give all the details I can see honestly, all without cleaning them up and painting them. Cleaning and painting is very time consuming for me, and my back limits me greatly on how many times I can handle these heavy buggers.

This unit here is a 31 spline, heavy duty 4 pin posi, with 3:50 gears. Some rust stained teeth, that will not effect the operation of the unit. I will send teeth pics if wanted via email. It will need a front pinion seal OR a sleeve for the yoke. Both are easy to do, and both are a $10 part each. I package these units safely, take time off work, and deliver to a carrier...(60 mile round trip), an extra charge because the unit is sent special handling because of weight, so I really cant cut a break on shipping, which in total cost me on average...$100. I need $400 for this unit.....FREE SHIPPING up to $100 Anything over that, will be applied to the total price. PayPal or Postal Money Order works the best for me.



The second unit below had a broken rib on the case that looked terrible, so I swapped the case out to a good extra one that I had. That means the backlash on the gears needs to be reset, and side load on the bearing caps before using. Its the exact same condition as the first unit described. I need $380 for this one, same shipping and payment as previously described. Thanks for looking.
