# of axle splines in an E-body stocker

I know that a strange unit went in the dakota to replace the 8.75 when I spent the dough on A&A protrans......They are both excellent and support the racers. Which one is closer for the freight savings?

Not to complicate your decision, but I pitted across from a index racer at the dutch who replaces his 8.75 r&p every 300 runs, not pro gear, as you can't get the 4.88 to my knowledge. I think he said $200 bucks or so at a whack.

Your other consideration is the 60 versus 8.75 resistance, I haven't found it to be different, and the weight difference especially going from drum to disc was nada.

60's now in the entire fleet: 70 challenger like yours, but a stick, dakota, dragpak, and the idle 72 which is waiting for some love. All are 40 spline but the 72 which is a 35.

I still have my complete 8.75 rear end 4.88 Moser axles downstairs at work. Might even be the Ebody width!

Thanks for the replies.

Well gents, getting the prices together really made this a no brainer. To "fix" my 8.75 will cost $1300 not counting my labor. I'd have to buy a spool/axle package, back brace, bearings, yoke, R&P, wheel studs, carrier caps w/needed machining according to mark williams website.

For a new rear end, components are: pro gear, 5/8 studs, spring pads welded, cast yoke, spool, axles. may go with a forged yoke though.

Strange: $2000, free shipping until end of yr.
Moser: $2400, + 225 shipping.

So for another $700 I get an assemble dana delivered. Just need to pick a gear ratio before I can order. Either 4.88 or 5.13. Motor package isn't figured out yet, but I think the 4.88 would be a safe start. Suggestions ????

4.88 would be a "safe" start.

I'm a small block guy and have seen many auto trans 3.58 stroke 360's favoring a 4.88 while the 3.31 stroke 340's like a 5.13 in Stock. Your 383 has a 3.375 stroke, so 4.88 should be safe and later determine if the engine and valvetrain can handle a 5.13. There are always 92.5" and 94" circumference slicks to experiment with as well as radials which will raise the rpms due to limited growth. But it wouldn't surprise me if a couple combos may go a step further. That's my theory and 2 cents worth. Now I'm curious if someone can confirm my theory.

See if you can find any Moser dealers in you area. Might get a better deal than buying direct. I lucked out to have a driveline place here in Daytona who also do my driveshafts. Or ask about "price matching"!
