had a tree fall on my winter beater xj only thing good was drivetrain its a 1998. was wondering about swaping my 98 4.0 into a 00-01 xj. is there any problems id run into?

 

Differences in the exhaust manifold, I can't remember the specifics.
They say the blocks are compatible, so I'm assuming the 00-01 sensors will work on the old block.

The big difference between 00+ and -99 is the distributor vs coil rail, so I'd figure out what needs to be done to deal with that.

 

that's what im worried about distributor to coil
