92 K2500 frame options

[TommyB1962]

Hi Guys, I own a 92 Chevy K2500 Reg Cab 6.5 TD. My frame is a little on the tweaked side and I would like to find out which frames I can swap with. Specifically, which frames my control arms will fit. I have the stamped lowers with the riveted(now bolted) ball joints. Will these arms fit onto a frame that came with the stamped arms and pressed ball joints or one with the cast arms? From what I've found around 95 or 96 they changed to a cast style(from timbren site) and I was wondering if the geometry was the same with all three arm styles. I would like to find a 98 frame from a pickup or suburban(same wheelbase) and switch everything over to it, refurbishing as I go. The end result is going to be a 68 Chevy c20 riding on a 92/98 K2500 frame with a 6.5 TD(MFI). But first I need to sort out my frame options. Any help would be appreciated.
