    Suppose I can check when I get home, but I was pretty sure.
    I recall specifically from when I was gonna retrofit a super 60 front axle into a k5 with a 70hd rear end.

    Good times.

    Can someone define the difference in a Chevy 8.5" and 8.6" rear end?

    I was looking over gearsets on the web for 10 bolts, I'm looking for 4.56's, but I'm finding gear sets for a 8.6" ring gear... Is this a typo?
    Or just some generalized terminology for the 8.5"?

    8.6 must be a later year 10 bolt axle.
    Am I right?

    Anyone know of a stout aftermarket axle shaft for the rear end?
    Regearing to 4.56, maybe Lincoln rear end.

    If youve got a 10 bolt id use 30 spline axles. I swapped my 78 12 bolt to an 87 10 bolt, i already had 30 spline axles so i bought an aftermarket clutch posi to fit 30, swapped in my axles and switched my backing plates and brakes to stay stock with the truck. Only other change i made was swappin in the posi instead of open gears, i kept the 3.42 ring and pinion from the 87 rear.

    I was browsing around on the web, seemed the 30 splines are the way to go.

    I believe you are correct sir, I think that the 8.6" is around model year 2000 and later in 1/2 tons

    Rear end out!
    Time to strip it down, regear, and if needed cut shock and spring pads off to relocate in the old s10!

    So, while @bucket was here in Salisbury NC and trading parts with me, he made a suggestion, to use the np208 in the parts suburban I have behind the 4l60e in my s10, to effectively change drop sides, thus eliminating having to cut the tubes and switch drop sides on the 10 bolt... I think it's a great idea. I will look into this, because if that's a realistic possibility, I'm gonna do it.
    And of course whatever modifications are needed to make it work (machine work etc) I can do them here.
    Maybe while I'm at it, I'll clock it down a little bit since I'm not going to be cutting the axle and kicking the pinion up at the same time...

    Yeah, maybe someone here can confirm, that 208 and matching 6-bolt round adapter should bolt right up in place of the S10's 5-bolt round adapter and 231? T-case.

    You may just have to deal with dropping the trans crossmember some and maybe clearancing the floor some too.

    I have the last transmission that was in the s10 sitting to the side, I'll have to pull the t case from the burb sometime and take that adapter and see if it works.... When the time comes, lll post the results


    To add to that, I think it's a np241, and there's the Manual shift variation that's a np233

    The adapter you laid hands on is a 4l60e to np233 @bucket

    I cannot recall if there is a 4l60e to np241 adapter, but I wanna say there was last time I put a trans in the s10 for the 3rd time

    Edit again: 4l60e/233 adapter has provisions on it for the shifter to bolt to.
