Making an effort this month to get back on this project. It's become very tight under the hood at this point but looking good. In the spirit of documenting specifically what I've done to merge the three trucks together here's some of the recent activity:
Steering column connected to the 05 steering box by using a 36 spline x 3/4 U-joint (Borgeson 113449) to a 3/4 double D rod (16 inches) to a 3/4 x 36 spline rag joint (Borgeson 053449) to the 05 steering box.
Extended the radiator fan shroud 2.75 inches to enclose the fan.
Connected the 96 power steering pump to the 05 hydroboost by using a 96 F-Superduty hose. I'm using the 05 steering box so the hose between the hydroboost and box is the standard 05 hose. I'm using a generic aftermarket power steering cooler mounted on the radiator support.
Used the complete 96 under hood wire harness and had to:
-Extend the wires for all the lighting on the drivers side of the truck
-Replace the side marker light sockets with the 78 marker light sockets
-The 96 has one extra side marker light, cut it out and tossed in trash
-Replaced the 96 headlight sockets with the 78 headlight sockets (all wire colors and stripes are the same for both years)
-The 96 turn signal sockets fit the 78 turn signal housings so no changes needed
-Used the 96 battery ground cables
-Made battery positive cables with military style battery terminals, copper lugs, 2/0 and 3/0 battery cable
