If it's a 55 first series it's a pretty easy process. DO NOT disassemble the whole front end as it comes off in one big piece if you want it to. It is a lot more work, messier, parts misplaced and if you want/need to throw the clip back on to check room/ clearance you'll be glad it's in one piece.
1. Remove hood and bumper. For the sake of room and bonked knees.
2. Disconnect all wiring from the front clip. Label all ends, roll it up and zip tie to the firewall somewhere out of the way. Headlights, generator, park lights, etc.
3. Remove fender brace rods from firewall and fenders.
4.Drain coolant and disconnect hoses.
5. Remove radiator support bolts. These bolt down the radiator support to the front crossmember. Should be 2 of them, but many of these old trucks were "farmered" and may have more than 2 after years of abuse.
6. Remove 5/16" bolts that hold the inner fenders to the cab toeboard. 3 /side inside the cab under the mat on the toeboard.
7.Remove the 5/16 fender bolts that bolt the outside fenders to the cab. Up inside the outer fender. Don't unbolt inner and outer fenders from each other. I like to remove the wheels for this step and the next.
8. Get two buddies (and some cold ones to enjoy after this part). One person on the grill, the other two on the outside of the fenders. Lift slightly, pull forward, tilt nose down a bit, lift clear the back of fenders over wheels ( you'll be glad now that you removed the wheels!)
9. Place the front clip somewhere safe, high and dry to store until you need it.
This process can take as little as 30 mins if you have practiced
Good luck!
PS- I'm sure if I forgot something that the Bolters will let me know.
A Task force truck will be very similar... Most trucks are like this.
Here's a picture of me moving my front fender clip.
