Take this with a grain of salt, but from other threads that I have read, it is my understanding that the 1999 and up Trackers were unibody & not body on frame.

 

I have found a 2000 Tracker 2door and am wondering if this will work? I have also found 2001 and 2003 model Trackers as well but they are 4 door. Would a 4 door frame work?

You need to find a 89-98 2dr. Better yet, you might want to find one with a bad engine and swap yours into it.

If you find a tracker with good floors and frame you may want to rebuild it instead of your own. The cross members on your old frame are easy to replace with pipe or square tubing. They sell most of the body panels a s reproductions on line. I used the frame from a 2002 under a 1994 it took a fair amount of fab work but is doable if you have the shop and tools.

 

First - be very careful when considering frame swaps - there may be legal issues that you will need to deal with - the VIN/Chassis number is on both the body and frame and if they do not match you could find yourself in a legal tangle.

Having pointed that out - let me continue - NO - the 2000 Tracker frame will not work - a 2000 Tracker is an SQ series vehicle (99~05 in the US) and the 94 is an SE series vehicle (89~98 in the US), SQ series frame rails are further apart than they are on the SE series.

Finally - none of the Trackers are unibody - all are body on frame. JB & JT series Grand Vitaras (2005 onwards), are unibody, but this model was never released badged as the Tracker.

 

I would also like to point out the caveat if you are going to be using a rolling chassis, rather than just the frame itself. If so, then you may want to consider the gearing - an auto donor will have different gearing than the manual tranny. In my frame swap, where the donor was actually a rolling chassis, the gearing of the donor was 4.88 - my original gearing was 5.12. While not a tremendous amount of difference, it was enough to be slightly bothersome to me, especially as my engine revs about 4% more in 5th gear than it did before. And you will also have to consider the braking system of the donor - if you currently have RWAL, you will want a donor that has that as well, as it works off the rear diff.

As an aside, unless the actual rails of your current frame are trashed (like mine was), the cross members are fairly easy to replace. What is the actual condition of your current frame??

 

I really appreciate all of the information you guys are sharing. It is helping me to think outside of the box. So I ran a camera down inside of my frame and it is definatley rusting from the inside out. When I started removing some of the undercoating I actually knocked holes in parts of the frame that I thought were solid. i was thinking if I could find a donor with a good floor pan that would help me to save on further parts.

 

Sadly, that appears to be how they usually rust out - from the inside out, and you don't really know, without a scope, until the damage is severe. That being said, if you weld, it is possible to patch, within reason. I don't know if you saw my frame swap thread:

If you look at post #2, the 4th photo down, you'll see a patch that a really good welder did on my frame, about 10 years ago. it was as strong when I did the swap, as it was when originally welded.....

 

The later framed worked for us in the shop, you have to rejig the body mounts and other bits and pieces. The unit the boys built was strictly off road so may not suit what you want. the pictures in your previous post do show rust but any thing can be fixed if you have enough money
