To give you a quick idea of the differences that I know between a F-2/350 and an Ex
Different front and rear shocks, different length and mounting
The fuel tank is at the very rear, behind the axle, in front of the hitch 44 Gallon. Same location a the 80-97 "rear" tank.
Spare tire is mounted INSIDE the cabin, left rear, like a station wagon, full size, does not store under the rear since the tank is there.....
Most of the running gear below the frame is the same as an F-250. Same brakes, calipers, etc...... The frame up is the difference. All Excursion came with a D-50 Solid Front Axle, and 3.73 gears (I believe). Most of the interior / exterior stuff is the same as a CC.... Front seats, dash, doors, overhead console...... etc... obviously the headliner, carpets and the like are different..... It is very similar to a CCSB F-250 body, but not exactally the same, as I have discovered over the years...... sorry.....
I will have to look about the hitch.... never noticed... it just hangs there and pulls the stuff I need.... never looked to see if it would come off...... will look when I get home.....
