4.0/2.5 parts compatibility

[Mcstiff]

I have a rolled xj with a 4.0 to pull stuff off of. So what will fit on my tbi 2.5?

Do you mean on the vehicle, or in the engine? The engines are of similar design, but not much interchanges. The bell housing bolt pattern on the two engines is different, and the trannies are different, so you can't swap those. Depending on year, you might be able to use the 4.0L transfer case in the 2.5, but that depends a lot on the respective years.

Radiators are completely different. Axles, brakes, steering, shocks, interior (except for front seats, again depending on year) and sheet metal all interchange.
