All we have to do is a simple posi rear end and gear upgrade in the 1968 Pontiac LeMans, that's it! Easy! We already have all the parts we could need sitting here and ready to go. After another expensive trip to our friends at Jegs we've got our posi-trac carrier, our install kit, and ring and pinion set. Unfortunately, as with absolutely everything with this car, that's not exactly the situation we're finding!
This Pontiac Project has been fighting us from moment one, from the first questionable purchase of the car until now essentially nothing has gone to plan. Initially there was some hope we could get it ready for the 2024 Pontiac Nationals, well that idea has gone completely out the window now it's just a question of can we get the car done without going COMPLETELY upside down on spending?

Corporate 12 bolt differential highly recommended 👍👍

On a serious note- If it were me: I’ve learned that you’re often further ahead by spending more money up front and replacing everything with new rather than cobbling it back together. The repairs rarely last I’ve found. I obviously have no clue what the price points are and you’re so far upside down in this car 🤷‍♂️ I forget where Pole Barn Garage gets his rear ends from but he speaks highly of them and the prices he says are fair.

I bought a SD-455 new in 74. It came with a 308 gear because of the air conditioning. I was told that it was necessary because a higher numerical gear would throw the belt. After the warranty was expired, I had the gear changed to a 3.73. I also added hooker headers and a B&M transpak and a Holeshot converter. When it was stock from the factory I ran 13.8 at National Trails on street nights. With the headers, converter and new gears, it would run 12.20's all night. So my experience is that for 1/4 mile racing, give it some gear.

Austin it has happened to all of us at some point. Sorry for the bad news. Rich knows his stuff. Thank you for sharing. 💕👏👊👍

The 8.2 is prone to break. See if you can find a used 8.5 and build it.

After hearing you say the body needs a lot of work and the frame isn't great, my (unsolicited) suggestion would be to find a better shell to hang your nice new parts on.

I’m not surprised that Austin’s rear end is nasty looking and all wallered out. I bet it’s seen a lot of action back in its day. Definitely been abused in the past on Saturday nights trying to impress the ladies. But he’s in good hands 🙌

I agree with the previous comment. Find a good used 12 bolt posi with some decent gears and go have fun. They are easy to upgrade and the parts are relatively inexpensive.

Super sorry to hear about the rear end. Obviously a built rear end would be wonderful but crap are they expensive! Checked on a Currie unit during HRPT,, $4,600,

I'd think in grand scheme a 9" from whoever would be called upon. Gearset for track an hour later different gears set for road. Plus plenty of aftermarket support if things go sideways. Yes lots of dollars but in long run

Could only image what the rear axle sounded like when it was rolling along..

Find another BOP for next year but do the build up here, Run the 3.36s and have fun at the Nationals.

Fix the frame rust or the new rear end will fly out. Looked like a decent amount of rot. 😢

Putting a Moser rear in this poor old Poncho would be akin to dropping a strawberry in a basket of turds. Never heard of a 350 HO. It would be one thing if you were doing all the labor on this, but buying parts and paying installation costs, you'll never break even.
