@XCM set this axle up for me last year. 4.10 Motive gears with a Motive Grip Pro limited slip.
Pattern looks pretty good. Ignore the edge of the teeth being clean, that's from grabbing it.
Going together with new Ten Factory 4340 shafts and Spicer 760 ujoints.
They come way better packaged than axles used to.
Going in with new Prime Choice bearings recommended by @Lowrange2.
I'm kind of tired of dealing with factory 13 point rusted out bolts, so I ordered up ARP 12x1.75 x 90mm bolts. They come in 5 packs, so 2 packs gave me enough for the car plus a fresh set to go with my spare unit bearing.
If you've never installed an ARP bolt, they have rounded transitions from the head to the shank, and a beveled washer to go with it. The washers have to be installed with the bevel toward the bolt head.
If you install the washer backward it will not sit flush against the bolt head.
I didn't have axle nut hardware, and since I had to buy something I thought I'd try something new.
First install, I think its a hair too deep. I installed it without a washer this time.
Added a washer and I like this better. You'll notice I marked the end of the axle in sharpie to mark the cotter pin hole.
And pinned home.
In retrospect I should drill these and install a cotter pin. I may or may not do that.
