Message: [QUOTE="Strokersace, post: 1511970, member: 622"] I've done several over the years. The last one I did about 8 years ago was swap an F150 supercab long bed onto an F250 powerstroke chassis. That sure turned some heads when people are saw the F150 on the fender but the rumble of the PSD! Interior and exterior are a complete swap of electronics. The big difference is the heat shield on the engine side and the sound deadener on the inside of the firewall. You can do the heat shield 2 ways: 1. Use the stock PSD shield. Either weld mounting studs onto the firewall like the PSD cab has, or hold it on via rivets and fender washers. I've done both. If you don't want to weld, then drill/rivet. If you don't want to drill holes, then weld studs. 2. Use an aftermarket heat shield product that has adhesive backing. This is what I opted to do on the F150 cab. I actually put sound deadener on 1st, then the stick on heat shield next. Actually takes up less room off the firewall than the factory shield. The other difference is that in the diesel cab, the out sound deadener product on the inside of the firewall. I didn't know this on the 1st cab swap I did and it was always noisier in the cab than other PSD trucks. Realized it on the 2nd swap. When you pull the dash and heater core components, there's a "closed cell mat" held onto the firewall with rubber push tabs that can be reused if removed carefully. Pull this off and it'll be the bare metal of the firewall. Put dynomat or the like sound deadening on the firewall as well. You can just do the hump behind the engine and down pipe or go all out like I did and do the entire inside of the firewall. Reinstall the mat, then the PSD complete dash, and you're in business. Good luck and post some pictures! [/QUOTE]
