Clutch flywheel and cps matching

I have a 91 ax15, with external slave bellhousing, that I am matching to a 4.2L slowly undergoing an efi conversion. I don't care that it's a 4.2 and not a 4.0, I just need to know some interchangibility.. The computer is from a '95 cherokee, and I'm going to mount the cps in the stock bellhousing location. do I need a 95 or same gen flywheel, or will the cps work with earlier flywheels? Also, are the clearances the same between different years of flywheels? I have a brand new clutch bolted the current 4.2 flywheel, but I'm going to purchase a kit because I need the correct pilot bushing and an alignment tool, neither of which can be found outside of kits. I know the kit must have the same gen pilot bushing as the trans itself, I just don't know if pressure plate bolt hole locations/diameters vary or not...

match the flywheel to the same series of computer. so in your case, try to find a 95 flywheel. theres a year or two that have one set of notches offset and i dont remember which style it was.

will a 91 clutch kit work with a 95 flywheel?
