The biggest thing you will notice, is the lack of aftermarket support for the Dodge trucks. Otherwise, the knowledge here is as good or beats anything out there on the internet. We all spend time on other websites, but this is where your truck will be the most at home. lol.
Bud is using a Dakota frame, but it involves replacing the orginal firewall with the Dakota's. I have yet to see a truck with the firewall that hasn't been moved, but that doesn't mean it hasn't been done. I was toying with the idea of moving the engine forward on a volare type front end, keeping the wheelbase the same, but the weight distrubution wasn't the best. So, I'm using a 92 Dakota firewall like Bud's.
