Shimano MTB left crank arm compatibility

So I have a M780/M785 left crank arm (Stages). I want to be able to use it with an old beater bike, and wondering what other old Shimano Deore/SLX/XT level cranksets will be compatible? Not looking to spend anymore than > $75 on the crank arm (really I just need a right crank spider/spindle). Planning to use a single chain ring with an old FD as a chainkeeper.

AFAIK just about all MTB HollowTech II arms have the same spline interface.

The right crank arm is not available as a replacement part.

Same spline but not the same fit. A XT left crank is not compatible with a XTR spindle, for example.



EDIT: I talked to Stages, XTR has a different spline depth, but XT and below should be interchangeable.
