1995 long bed to short bed conversion kit?

[LS short box]

I'm in the market for a new hot rod project and I'm considering a 95 Silverado 2WD long box. Supposed to be a "rust free" truck from Texas.
I would be converting it to a short box. I did searches but I'm a bit confused on the best way to go frame shortening wise. I know on 67-87's they cut the frame with like a LMC kit. Does a 1995 frame conversion work the same way.
I've also seen some posts on moving the rear axle forward and then just cutting the back of the frame off.
I'm not afraid of cutting welding the frame or drilling rivets to move the axle forward.
I haven't bought anything yet just trying to plan ahead.
Any help would be great.
