short box measurements

[skymangs]

I have an AD truck with no box (it was a 3600 flatbed). The truck is now on a 91 S10 frame. I am suddenly concerned that a shortbox may be too short. can anyone give me measurements from the rear wheel center to the back of the cab, and from the frontmost portion of the rear fender to the back of the cab from thier shortbox?

the frame I used is a 117" wb short cab/long box 2wd S10, and I hear that the shortbox should fit. i've seen some builds that have a rather large gap between the box and the cab, and i don't want that. So I'm trying to decide whether it would be better to cut down a long box, or will the short box be just the right length. I just want to be sure before I buy one.

thank you,
