This is the official kickoff of the Bumpside Build-Off between Classic Trucks and Custom Classic Trucks magazines. If you don't know what a Bumpside is, it refers to the '67-72 Ford F-100s-they have a distinctive bump down the side of the truck as part of their unique styling. After I bought my '68 F-100, the new editor of CCT, John "Out on a Limb" Gilbert, bought a '72 F-100, and we thought the right thing to do would be to have a friendly competition.
We have a year to build our trucks with our own hands and a little help from professionals. Each truck will be built in a different style so we don't repeat each other, and we'll use different parts as much as possible. We'll debut them later this year at an undecided out-of-state event where we might even take votes for which truck people like the best. These F-100s have always been lost in the shadow of Chevy's ultra-popular trucks of the same period, so we're going to do our part to bring this alternative to light as we buck the Bow Tie!
We ran an introductory feature on my '68 in our Sept. '06 issue that outlined my plans, which are still about the same, and I'm starting off with a bang. I gotta get rid of one of the biggest reasons people steer away from building these F-100s-the twin I-beam front suspension. They're tough to lower, and you'd still be out a bunch of money doing so, which makes installing an IFS system look like a practical solution. Fatman Fabrications has a Mustang II kit for the '61-79 F-100s to do just this. It works well and isn't too hard to install. Hey, I did it, and the only physical help I had was lifting the front sheetmetal from the truck! Fatman's kit uses either coilovers or ShockWaves and is available with several disc brake setups, or you can use your own that fits the Mustang II spindles. Steering is upgraded to a power rack-and-pinion system, which will be a welcome change to the worn-out manual box in my truck.
Installing Fatman's IFS is something that could feasibly be done in your garage if you have a 220-volt MIG or TIG welder and basic fabrication and measuring skills. The most important thing during all this is to take your time. Measure and check that all the dimensions and angles are correct, and have a qualified friend weld it up if needed. I don't want to sound like your shop teacher, but make sure you use all the safety measures one should for a job like this, and read the directions 20 times if you have to. Also, feel free to call the folks at Fatman with questions-I did, more than once. Unfortunately, I don't have a picture of the new front end with the wheels back on the truck since I'm waiting for brakes from ECI, and American Racing is just getting their new AR 500 wheels into production, so bear with me!
Next month, we'll tackle the steering installation and figure out if the stock column is gonna stay or go. Follow along as we highlight the process, and go out and buy a Bumpside while they're still cheap!
 The talented hands of artist...  The talented hands of artist Jimmy Smith put our visions on paper to share with all of you. Don't they look cool? Mine definitely has a late-'60s to early-'70s thing going on with a modern twist. The period paint might not be to everyone's taste, but it's something I've always wanted to have on a truck. Pair that with the new 18-inch AR 500s from American Racing, a fuel-injected DOHC Ford V-8, and a six-speed from Keisler Engineering, and I think we have a winner! |

 It was time to kiss driving...  It was time to kiss driving the '68 goodbye for a while, since I'm not stopping at the Fatman Fab IFS. I'm not missing much of a ride, though, with its slipping clutch, unpredictable brakes, a rod knock in the 360 that sounded like a Howitzer, and a worn-out steering box, but for $600, I can't complain! |
 Before tearing anything apart,...  Before tearing anything apart, I made lots of reference measurements. Get a piece of paper or a notebook and log everything. I measured things like the height of the wheelwells, wheelbase, and the height of the frame in the front and rear on level ground. Using the same factory holes in the frame from side to side makes it easy to get consistent measurements. |
 After removing the hood, disconnecting...  After removing the hood, disconnecting the wiring, draining the radiator, and unbolting the fenders from the body, the front clip was removed in one piece, which reduced the scattered parts (for now). I took lots of reference photos during disassembly, since it might be a little while before it goes back together for good. |
 Unhook what's left of the...  Unhook what's left of the drivetrain controls and yank it out! |
 These tape measures are kinda...  These tape measures are kinda tough to find, but they are worth the hunt. They only go to 12 feet in length, but you don't really need more than that for chassis work, and the best part is, they are in fractions on top and decimals on the bottom for quick and more accurate measurements. You can check things down to .100 inch or even .050 inch. |
 To get the axle's centerline,...  To get the axle's centerline, I clamped a straightedge across the same spot in the frame at the core support mount holes and measured back to the kingpins' center on each side. |
 Normally, finding the axle's...  Normally, finding the axle's centerline wouldn't be a problem, but I was getting measurements that were off by about an inch side-to-side. Every picture tells a story, and after scratching my head for a little while, I looked down at the radius arm bushings under the frame and found that the passenger-side bushing was pretty much nonexistent and the radius arm was pushed all the way back. To get my centerline, I measured the placement of the other wishbone in its mount and used a ratcheting tie-down to pull the I-beam forward, and it was right on. |
 With that out of the way,...  With that out of the way, I could remove the stock suspension and get started cleaning the grease and dirt off the front of the frame. What fun! |
