S10 frame swap questions

[Lookin4the1]

I know this is a heavily addresses topic on here, but I've gotten down to the frame this afternoon, cut off the appropriate body mounts and now I'm staring at the frame horns. How much do you normally cut off? Anything else I need to do before building my mounts?

cab and fenders are the same, usually the bed on a 3/4 ton is a long bed so you will need to shorten it about 10 inches if you are using a longbed s10 frame.
