K frame mods

So what i gathered from an old thread which I can't even find now about k frames is to touch up all the crappy factory welds and reinforce the lower control arm pin sleeves.. well kinda.

I am using my spool mount slant six k frame as a guinea pig here and I'm trying some stiffening ideas and anything to over restore these cars

I'll add more as I go along because it's a current work in progress.
