Open vs limited slip

[Call Her Bu]

I have a 350 crate/th350 trans. I have bought a set of Richmond 3.42 gears and have a chance to get a Yukon diff carrier for $150. I have a 1978 Malibu all stock for now. When I check fitment on Summit it says it won’t fit. I thought all Gbody rears were interchangeable? Question is will it be good enough for a weekend cruiser? Not really going to take it to the track. Maybe occasionally step on it or do burnouts. I have 18x8 Torq Thrust II with 245/45.

If you have the 7.5 still, you're going to want a 26 Spline Series 3 Differential Carrier.

See if it says that.

It’s a 28 spline. Thank you for pointing that out.

Just get the Moser 28 spline axles. Those axles will get that rear about as strong as it can get.

Here's the Moser axles. Not sure off the top of my head what to do for studs. Yours should be 7/16" x 20, and the stock size knurl would be too small for the Moser ends. I believe they are drilled for the '82-'88 metric studs. Maybe someone will chime in with a solution.

I thought these cars were factory 26 Spline but then again that might be S10 and Fbody stuff that was.

Yes, as far as I know that is true, but the diff he's looking at is a Yukon brand. Hopefully he gets the right axles for it.

That's exactly it right there, I read that part I was telling him what would work with the factory axles.

Would highly recommend upgrading over the stock axles so that extra $150 just turned into an extra $500+.. which is the law of cars.

I might have to reconsider and just buy a different carrier.

As far as limited vs open which is better for weekend cruising?
