how about some pictures.
You will want gearing in your axles of at least 4.62 unless you are going with a 4.1 transfer case.
I would swap the whole engine out of the tracker into the sammy.unless of course the engine is shot.


I drive mine every day to work I'm running SPOA. 1 inch lift shackles and 4.62 gears in the axles.
the 1.3 still struggles to get my 32's up to freeway speeds.
I would also recomend power steering which I really need to get into my garage and finish.
also dodge neon seats almost bolt right in to the sammies. but that is up to you since you have the tracker.
Use the search funtion it provides great knowledge.
anyway hope that helps a little.
