i was wondering if anyone out there knows if a transfer case from a 1994 tracker willl bolt into a 1990 tracker? any info would help.... thanks guys

Yes, it will.  They are the same.  The only difference may be that the 90 will have a Low range switch on it to indicate when the transfer case is in low range, where the 94 probably will not.  If you want, I believe you can swap the switch from the 90 to the 94.

haha thats a relief ... i assumed they would ... but i probably still should have checked that before i bought the 1990 haha ... thank you very much for the info
