No they should not fit, 1990 is a YJ, and 1998 is a TJ
Yes, it will fit just fine.
No
1990 Jeep
No, those do not match. For the 1990 look at the years 1987-1995
No.
Certainly, they are both YJ"s.
no it wont fit cause ive just changed a 1990 jeep Cherokee transmission it had a 1998 jeep grand Cherokee transmission in it it broke the fly wheel and burned the torque converter up
if they are the same engine then yes.
Physically it will fit, but the engine will not bolt up.
yes, any top for an 1987-1995 can be switched out
It will fit 2007-2013
