It's been a long time since I worked on an ABS 900 so I can't recall if the ABS CV joint plugs into a non-ABS hub without issue BUT I think that is the case. Does your donor car have ABS?
It appears that new tripods are available (the later, big ones) and I've always had good luck disassembling, cleaning and repacking old CV's and new inner and outer boots are available too. CV's will often behave like they are badly worn when in fact all they need is dirt out...fresh grease in and a good genuine OEM CV is the best CV you can have. Consider doing that with your 1986 axles. There are lots of horror stories associated with "rebuilt" exchange axles.
You can disassemble and restore a tripod as well (don't lose any needles). Just push the rollers off and inspect the needles, spindles and rollers for wear. If there's no evident wear or damage rebuild with fresh moly grease and you just save $50! Each roller/spindle must have a full compliment of needles, no gaps or it will vibrate and wear out fast.
The way to check the inner driver is just feel the surfaces of the slots where the tripod rollers live and see if they have notches worn in them. Feel all six faces. If they have notches find some good used ones. Saab used to tell us that, since the notches develop on the drive faces that we should swap them left for right, putting the wear notches on the coast faces, to get more life from them. Eriksson Industries used to weld them up and grind them back but that was a while ago.
If you need to deal with a worn inner driver it's best to replace the oil seal, o'ring and maybe the driver support bearing while you are in there. Do one side at a time (if you are doing both), replace the shims just as they were and put some thread sealant (like #2 form-a-gasket) on the six securing bolts. Be careful with the snap ring. Set the driver assembly on a bench and smack the snap ring downward to un-pinch it before trying to spread it. If it won't spin around the shaft don't try to spread it or it will get bent. On reassembly check that it spins freely in it's groove. If it's not seated the inner driver could wander outward from the unit and cause axle problems. The small driver support ball bearing is often overlooked and a worn one will cause a bad vibration and transmission oil leak.
I just put a fresh engine and transmission in my 1986 SPG yesterday.
