I believe it will. Here is from QS tuning.

Stock Turbo Rebuild Kit

Complete service rebuild kit for your stock 6.5L turbocharger. Genuine OE quality by Clevite Mahle. Works with all GM4, GM6, GM7, GM8 turbos.

At least the bushings must be the same sizes, unless there would be a difference in shaft lengths.
It appears that the threads on the shafts must be the same too as the wicked weel fits from 92 on up.

Wicked Wheel 2 for Stock Turbos

Billet upgrade compressor wheel for all stock GMx turbos. This includes all 1992+ 6.5L that have a factory Borg Warner turbo. These will NOT fit aftermarket replacement stock style turbochargers. These are a great upgrade for the center mount style turbos that are hard to swap to different...

Have a feeling I it could be a match...but I wanna be sure before I spend the cash and take on the work of opening another turbo as well!

Next month I`ll be getting the fluidamper for My truck then the next thing is going to be that turbo kit and the wicked wheel.
Maybe someday I might go for a bigger turbo, the biggest problem with that is almost all of My driving is in the 65 MPH range and that is right about 2000 RPMs, right at the very low end of the bigger turbos.

Bigger doesn’t have to be biggest. If you’re not crossing the 2,000 mark often, then an hx35 might be best. It’ll still outdo the gmx upper end and can light up just as early.

On a facebook site there is a HT60 turbo for cummins N14 for sale for $350.00. I dont know enough about the turbos to be able to tell if that would be a good match. Being it has that 60 labeled to it, probably be too big.
Eastern Montana Man Stuff if doing a facebook search but then have to join to get in, I think that's how it works.

That thing is sized for a 14 Litre displacement Cummins in a semi. But hey, get your 6.5 up to about 6,000 rpm and you MIGHT get that HT60 to light off, @MrMarty51 !

Maybe come up with two 6.5s end to end, call it a V-16~13. That might be able to spin it ? ? ? ? LOL

What an intake/exhaust plumbing and fueling nightmare THAT would be! Let alone what the hell would it fit in? (Hmmm, two front clips welded end to end on an extended frame for a seriously stretched nose on a dualie crewcab long box?)

Might make a good unit for a motorcycle.
