We started my removing everything off the firewall that wasn't going to be reused on the truck. Then we cut out pieces of sheet metal so that every hole could be welded up and smoothed out. One the inside we primered the whole cab with primer and any area's we couldn't get to we used a rust converter primer to seal everything so we would have no issues down the road. We also re seam sealed all of the firewall seams.

We then needed a solid mounting plate for our throttle pedal and TAC module that Spalding Autoparts sent to us. So we welded one up out of 1/2" tubing and welded nuts on the backside to secure everything. Once this was welded to the firewall, we seam sealed it and primered it also. All of the primer and seam sealer was from Duplicolor.com.
