I myself personally would decide based on how much I have spent on the 4x4 already. If you have the cash to rip it out and re do it with a 2wheel tranny, then go for it!
sell it and get a 2wd for alot cheaper. gonna save you some money but more importantly ALOT of time. Unless if you want to make it all wheel drive and laid out. dont know if its possible but its worth taking some measurements...
I have a 2wd s10 frame for a regular cab with nothing on it, just a frame thats notched and the front frame horns are dropped 3.5" for a body drop. Call me or email me if you are interested my cell number is 636-577-1871.
