1989 Drive shaft questions - Please help

[60 Biscayne]

I have the drive shafts out of a 1989 Wrangler that was a 4.2 with a 5 speed transmission.
I have a few questions:
1) What years are the same? ie; 1987 to 1995 etc......
2) Are the 4 cylinder Wrangler shafts the same length ?
3) On eBay a guy selling has indicated that a Wrangler & Cherokee are the same? Is this true?
Thanks, Jim

'87-'95 are all similar model Wranglers (YJ) with minor differences between years.

4cyl and 6cyl YJ's will use different length driveshafts, as well as differences between auto and manual transmissions.

Cherokee (XJ) and Wrangler (YJ) driveshafts will not interchange.
