Agree!
I have 28 spline KA axles with a Detroit Locker from Tom's Differentials.

Hmm.... 7.625 must've started in 85 then. All the 85-88s I've seen had a 7.625. I thought they were all 3.73... learn something everyday.
S10s also have 7.625" R&Ps and 28 spline axles; swapped an Auburn posi carrier into my wife's '02 Camaro.
Correct, depending on the build date. I was told some early build 88 F body and S-10 family had the 7.625 with 26 spline axles. 1988 was change over year for GM.
As explained to me the 7.625 ring gear added .125 to the overall ring gear diameter, In a G Body no changes to the housings or the carrier were made to use this "wider stronger" gear. All the 7.5 housings and carriers would accept the 7.625 parts.
I have to admit....I laughed at that "wider stronger" statement!

Would you know if the side gears for the 28 spline would fit the 7.625 carrier they used in the SS. I wonder why GM would use the 26 spline with the 7.625 carrier in the SS when they had 28 spline available that they used in the 442 and GN.
I believe a few years ago SLP was selling 28 spline Camaro take out posi's for $100.00. A 28 spline eaton carrier is about $400.00 and the Moser axles are about $250.00. Most of the 8.5" s I've seen seem to range $800-$1100
Because they are two totally different rearends?
The 26 spline had been in service since the 7.5 came out in Vegas and weak-sauce Nova six cylinder cars.
Monte SS cars did not break rearends religiously. Not real sure why or how the 442 ended up with the 8.5 though.
*You could get an optional 4.11 ratio in Monte SS cars.
The ONLY 28 spline axles that fit are 8.5 G-body axles, there is NO junkyard mystery swap.
So, to reiterate this back and forth nonsense, the 80s monte SS got the OPTIONAL 7.625 rear end in 1985, with 26 spline axles, with a range of different gear ratios (I don't know them all other than 3.42, 373, and apparently 4.11), and the 7.625 only got 28 spline axles in 1988, the last year of the g body monte SS... right? Man the OP of this thread's gotta be annoyed, eh?
