I'm not familiar with anything newer than 1993, however I read a lot....
AFAIK you need to find the same basic truck as you have. IE; 4x4 extended cab. I believe 98 and up will work. 4x4 and 2wd use different front suspensions.

Very generally speaking the 83-97 frames are about the same, there were major changes in 98 and they stayed about the same until end of production in 2011. For your 2002 you will need to use a 1998+ frame.

There are three frame lengths in this time frame
1) Regular Cab Short Bed
2) Regular Cab Long Bed
3) Extended Cab Short Bed

In each of those you had 2 versions primarily referenced by the front suspension style:
A) Torsion Bar (all 4wd and some 2wd)
B) Coil spring (only 2wd)

If you want to replace the entire frame of your truck you will need to find an extended cab torsion bar frame.

If you want to replace only the rear half of your frame it may be possible with the proper measuring and cutting to use either of the short bed frame options and 2wd or 4wd won't matter.

I'm not sure of the year when it began, but some 98+ Rangers used 2 piece frame rails that were riveted together (IIRC) right at the front spring hangar. If you separate the frame there you should be able to use either a regular cab short bed or an extended cab as a donor. Use appropriately sized grade 8 hardware to join it back together.

1998 and up short bed frame is what you need. If it’s only bad from the front leaf spring hanger, any short bed frame will do in that year range. There are 8 rivets holding the frame sections together. 2 top, 2 bottom, and 4 through the hanger. There is also a crossmember there that holds the rear gas tank strap and the muffler. If you need more frame than that, you’ll need an extended cab frame and either do a cut and weld or get a full 4x4 frame. If you cut and weld, make sure it’s done right with a good welder and fish plate over the repair.

Torch or grind the rivets down and beat them out or drill them out if you go that route. Replace with grade 8 bolts.

I just did this with my one Ranger earlier this year, be prepared for a bit of work. I got the rear frame section from an extended cab 2wd because it was in beautiful shape and the cab and bed was stripped off it already, making my job easier to get what I needed.
