I've been measuring and sketching, so far the S10 long wheel base regular cab is the best fit. I've been hoping to find something to drop my 50 1.5 sheet metal on and I'm currently at a loss most late model (72-on) are too wide. Current plan is to mod late model parts to fit the stock frame which is in very good condition. Grigg has great info on this.
