Scott I have an '89 K3500, but that's the only '88-'98 1-ton I've ever looked at very hard. I don't know what the two wheel drive type looks like, but since I'm not inclined to narrow the IFS at all its not like the C3500 would solve my problem.
I think if I had one, I'd be considering using the entire chassis.
I've received a reply from the guy who wrote the material FastEddie pointed at. He lives just off I-5 in a town I need to pass through in a few weeks. It looks like Steve will buy Steve coffee and talk about truck suspensions.
