Suntour Accushift freewheels or cassettes are for index. Sorry I don't know part numbers.

I doubt it .. Indexing being Shimano dominated, And Suntour is RIP as a parts maker now ..
You will find other companies like Sun Race making freewheels with the hyperglide like tooth profile ,
IRD is another importers brand.
but then the spacing changes from 7-8 speed ,
Only friction shifting lets you mix and match at will.

What I mean is, are all the 4 prong Suntour freewheels (Accushift) compatible?

Sun Tour 6s and 7s freewheels have the same spacing as Shimano 6s and 7s cassettes so yes they're index compatible. SunTour introduced their index system, Accushift, during the freewheel era.
But the 6500 freewheels are narrow 6s (ultra-6) with the same separation as a 7s freewheel. They were made to put a 6s freewheel on a 5s 120mm hub without respacing. You want a 6000 freewheel for 6s spacing

Accushift freewheels have variegated spacing.
Sheldon brown has a crib sheet of cassette/freewheel spacing:

sometimes you remind me a of an old coworker. if the part was not on the shelf or porduced in the last 6 months it never existed to him and you should throw the bike you need it for away for all he could care.
this is what happens when people do not get their daily allowance of "Bike Forum Classic and Vintage" threads.
to the best of my knowledge yes. all 4 prong 6spd FW are 6spd index and all 4 prong 7spd FW are 7spd index compatible

Still the answer is no, because only an accushift freewheel is spaced correctly for indexing. I had a 6 speed accushift drivetrain and remember going through this whole deal, I was lucky enough to find another accushift freewheel on ebay.
I think suntour only made a 6 speed index freewheel and that's it, all their other indexing was cassette. I think.
