Can an S-10 swap be done with this frame?

[fencepost]

My dad has a 98-2000 model 4 door S-10 jimmy 4x4. Been reading up on the S-10 swaps and love the ideal. He has no intrest in this truck but the running gear is flawless. It has a 4.3 4x4 with overdrive tranny. Haven't been able to find anything on a 4x4 swap other than the rears are what people want. Can anybody shed some light on this question? He also likes flat beds just now thought we could do the truck fenders and cab with a flatbed maybe? Thanks.
