Having used the search feature and reading through a few threads you will find that WJ and ZJ Grand Cherokee seats will bolt onto the 1995.5-2001 XJ Cherokee seat base/floor slider (power or manual). If you want power seats in your Cherokee, you will need XJ Cherokee power seat bases to bolt you new seats onto. If you find a set of Grand seats with the power recline, you can wire that feature to a separate switch.
I see no reason why the power recline seats wouldn't fit the Cherokee seat bases, but my WJ seats in my 2000 don't have the power recline function, so I can't be 100% sure.
