So I'm getting ready to do a 700r4 swap, I have almost everything figured out and then the shop tells me I should look into doing a Moser 12" as I will be snapping my axels on the 10 bolt soon after otherwise. I want to do a 3.73 LSD rear but I can't afford the Moser ($2300+) at this time, looking at just a carrier for now. The engine makes, at max probably 325 tq on 215/70r14 BFG Radial T/A so no slicks, and will only see a few races maybe 10 in the next few years. Should I be concerned or might it last me till I do the Moser?

There is no Moser 12".

325 tq isn't that much. My stock 350 TPI was making around that at the ground. I was using a 9 bolt, but still. Slicks is what is hard on things.

oops, I meant 12 bolt, I've been looking at so many rear ends lately that they are blending together

But I should be fine with the stock 10 bolt for now? If I had the money I would go for the Moser ASAP but it is not financially practical, neither is a 700r4 unless I weigh it against gas prices and what I will save there.

It's a toss up. Sometimes they break sometimes they don't. Just depends on luck. But yes sticky tires and hooking hard puts a lot of pressure on things. 26 or 28 spline axles are small no matter how you look at it.

Alright, I might just bite the bullet then, its not usually driven too hard and will hopefully last

Not to worry.

Those no-traction tires will protect the rear from ever seeing enough abuse to suffer any damage, with the exception of tearing up the small gears with one-wheel-peel.

Not sure if you are saying I have a bad tire choice, or that since they are not designed for true traction like slicks becuast my BFGs have been my best tires I have used yet, granted I used Hankooks and Futuras before so my selection hasn't been the most amazing,haha.

But thanks Sofakingdom, you have been a big help in getting the info straight with my posts and other posts I have read

Yup, pretty much; the cheeeeeeeeeepest of the cheeeeeeeeep.

I remember screwing up and buying a set of those in about 85, when my 83 got around to needing new shoes. I thought NOTHING could POSSIBLY be worse than the Goodyear garbage they came with. Boy was I EVER wrong. I hated those POSs from the instant the car came down off the rack. I threw em away before they were half wore out, just to get rid of em. I doubt I got 15,000 miles out of em before they went in the trash. A bunch of slippery, greasy, impossible to drive in the rain, inferior TRIANGULAR excrement. If memory serves it was the triangularity that finally tipped me over... I got so sick of the constant wubbawubbawubbawubba that I was ready to open my veins.

Problem nowadays is, the wheels that came on these cars are SO TINY, there's no good tires made for em any more. The whole "performance tire" industry has long since moved on. Got to the point I bought a set of C5 wheels for my 83, so I could ACTUALLY BUY good tires for it. Ended up with Pirelli P0 Nero in the stock Vette sizes, I forget what they were; something (don't quote me on this) like 275/50-17 and 345/45-18. But they don't make any of the better tires like that, to fit these old pizza-cutters on our cars.

You'd be AMAZED at the improvement high-quality tires can make to every facet of your car's performance. Michelin, Pirelli, the better Bridgestones, stuff like that; REAL PERFORMANCE TIRES, as opposed to ... those others.

Well IDK what it is man, but these have been amazing for me. held up for almost 2 years now which is my record as I was swapping tires like mad. They have handled great in rain and snow for me and would only break loose in wet roads if I dropped to first and slammed the pedal. But like you said, it's a hard task to find decent tires for such small wheels. Once it's in my budget I will be going for a better wheel/tire setup but these have been good to me thus far.

If your car is a '82 then you have the smallest 26 spline axles. When you upgrade the differential I would recommend also upgrading to the larger 28 spline axles. It might not seem like much, but there is a big difference in the strength of the 26 and 28 spline axles. Get a 28 spline Eaton Posi, Eaton Truetrac or Yukon Dura Grip (no Auburn) and a set of '90 to '92 axles and you will have helped the rear end out quite a bit. It will still be the small rear end, but with hard street tires on it you shouldn't have to worry about breaking it.

My only problem is I want to keep the rear end on a budget for now, the 700r4 swap is gonna put me back about $2000 and a new posi carrier will be at least $300 plus $850 for the 90-92 back end if I order from Hawks, I will check if maybe a local junk yard has one for cheaper though. I will get the 30 spline once I have more funds available.
