Replacing the seats.
 

My 99 has the stock seats with the manual lever underneath, can I replace them with the programmable seats from a 98? If so, is it easy?

What color are your seats and what is their condition?

Mine are camel or savannah beige in color and the leather is cracking/falling apart.

I believe it is cheaper to just get used replacements rather than recovering them.

Ya, a pain in rump as for full functionality. . Rt. is Not to hard for simple functions, Left is takes some grit and study of wire diagrams.
