I recently was given a 95 geo tracker that was wrecked .
My question is what is swapable to my sami and what type of mods are required (for moter and trans)?

trailtuff sells an adapter plate .somewear around $160.00 . the front tracker 3rd member will fit ur sammy. the tracker has 4-60 auto,5-12stick,ring and pinions.samy has 3-73r.n.p. if ur just offroading you can cut spring perches off tracker rearend and go to a trailer suppily co. and buy som leaf perches for around $4.00 a piece and fit tracker rearend under sammy.
or u can cut axel tubes off tracker rear ,cut axel tubes off sammy rear and weld sammy tubes on tracker housing.this is difficult even with fabrication skills.but you can also buy them from trailtuff, and maybe a couple other copanys. i would recomend taking the ring and pinion out of the tracker front 3rd,and installing it into sammy carrier.sammys stronger.

just call trail tough, they have a special on the wiring harness and the trans adapter,you need to pull the whole harness out of the 95 and send it to them and be carefull with the ecm, you can use the engine,starter,exhaust manifold,wireing,ecm,power steering box and pump,rear axel housing and third,front diff,u joints, steering wheel,steering shaft,tank?,rims and tires, brakes?depending on how you mod the axel,trans and transfer case if you go to ott and have the x-fer case  modified.(dual case's)
