I just saw something you might be interested at Speedway. (Try
www.speedwaymotors.com). They do list our stovebolt trucks for modern front end kits. It's only $300-something bucks. I was surprised. Comes with disc brakes, upper and lower control arms and springs, rack and pinion, and is available with a 2" dropped spindle.
If they could upgrade to 8-bolt wheels, I might try that myself!
