made progress this weekend but I am also scratching my head. I welded in the firewall and floors and also hung the doors for the first time since I had the truck. I bought it in pieces. I mounted the firewall with screws and put the cab back on the truck so I could locate my motor and weld in the mounts.
and now after it is all welded in the firewall hits the motor. I installed a bitchin firewall and floor kit that came with new front cab mounts. I measured every thing twice before I welded them in. the cab fits fine on the frame, front and rear mounts line up perfectly. I will try to install the motor again tonight and just hope I was having an off day.
