GM C20/C30 Cradle/IFS swap?

[lobuck76]

I've got the '79 f-350 sway bar on my '71 f100. It helped some, the front end is tight. It still wants to dart around when you make a wide curve on the highway, I think it's an alignment issue. Maybe the caster is off some.
Mine drove much better before the disc brake conversion. The kingpins were tight on the doner truck, so I swapped the I beams and all. I think a trip to the gray haired front end man will fix it.
