Well I guess there’s more than one way to skin a splash pan, and you can count on me to choose the least practical or popular way. I write that with zero knowledge of any other method, I just tend to get pulled in by considering all the abuse that flimsy panel might encounter. And if that weren’t enough to squeeze the brakes on further reading, this project is going to be presented in two parts!
The metal pan that came with Bruce had a long history of abuse and was barely hanging by a thread when I picked him up in Colorado last June. The driver’s front quarter had been crunched at some point and mostly repaired minus the splash pan. I was already shopping for splash pans on the way back to Florida. So I ordered a fiberglass pan from Jeepster Jim, advertised as “used” for $$$ plus shipping $$ and it soon arrived in just two layers of bubble wrap amazingly undamaged. It hadn’t been drilled so it probably wasn’t used but lord have mercy it was less rigid than a potato chip! Well I can’t imagine a scenario in which the splash pan DOESN’T get STEPPED ON! Hell, I’M PLANNING TO STEP ON IT! So there’s the challenge and the reason for the two-part thingy.
First, let‘s take a look at our store-bought masterpiece…….

Too bad the glass guy didn’t take a couple of passes over this specimen with a chop gun. That might have retailed for $ but it would be worth $$ to the average Willysite. To me it’s just another task in a myriad of tasks that keeps my brain engaged. After a test fit to see if my bumper plan wrecked the splash pan plan (hah!) it appeared that the fit was reasonable and my goal of adequate drainage was reached. I noticed a nice hole in the lower flange of the grille below the parking light hole on both sides of the grille. The flange seemed strong enough to lash the pan to so I grabbed a strip of .312x3” aluminum I horked out of the $1-a-pound bin at my favorite metal monger last trip. After cutting it to 5”+/- x 2 pieces, I clamped it to my makeshift hammer brake and pounded a 15 degree bend into both pieces. I’m telling ya that .312” bar did NOT want to bend. That’s good, right? Then my devious side took the lead by drilling a legion of holes with the step drill, but only going halfway deep on the next-larger size. Just take a gander at the results……
View attachment 100207What you see above is 8 funky countersunk holes, 2 holes for bolting to the grille flange, and one special hole for the exposed carriage bolt that the factory specified. Let’s keep moving to clear up the mystery countersunk holes. The drilled bars were then bolted to the grille flange with the long end pointed toward the bumper, The pan was then notched on each side to fit over the bent & drilled bars. The carriage bolt holes were then drilled and bolted. After that, the flange bolts were removed and the assembled unit was placed on the bench for marking. This crap is just too dry, let’s gawk at a picture……..
View attachment 100208I wrote all that to write all this. Note that temporary dams have been clamped on both sides of the bars. The bars will be imbedded in a glob of MarineTex epoxy. The epoxy will squirt up through those 8 funky holes which will act as “rivets” when cured. Neat, huh? The blue tape will provide location accuracy and a temporary bolt will provide clamping pressure, acting against the earlier cut notch. Now here’s yet another trick, the clamping bolt MUST be drenched in paste wax so the epoxy won’t trap it. Behold the waxed bolts waiting to be shoved through a glob of epoxy…..
View attachment 100209View attachment 100210Let‘s see how that absurd plan worked out…….
View attachment 100211Ahh, perfect. Remove the dams, pull the bolts, and sand it purty. Next I focused on adding strength to the front edge. There was a piece of 1” steel tube w/.062” walls left over from making floor supports that fit the bill. It should be strong enough to hold the crooked pan straight in addition to some concealed brackets from the bumper bolts to the tube. Due to the radius molded into the bottom of the pan, some unconventional cutting and fitting and fastening was required. The two exposed bolts already drilled in the bumper will be the only exposed fasteners in the front edge. The steel tube was slit, bent, and welded to conform to the angled front edge. In order to line up with the existing bolt holes in the bumper, the pan lip had to be partially removed. I did the cutting with an air body saw, BUT with a helpful customization! A wide sawzall blade was death-wheeled to conform to the air saw chuck size. This is a good trick to add to your bag……
View attachment 100216Now it was time to get on with fitting and drilling and gluing and riveting. I do love those rivets.
View attachment 100217The area outlined in red shows the boogered up situation created by the necessary position of the tube. This will be purtied up later. Oh yeah, the tube ends were plugged with hardwood which made it easier to fit the complicated molding. Let’s get on with the riveting…….
View attachment 100218Now we need a form to cast some MarineTex along the front edge to finish it off. A strip of .5” x 1.5“ plywood would do nicely, and to keep the epoxy from sticking it was covered with a strip of packing tape which was then waxed……
View attachment 100219Nice! The tube was set in a bed of epoxy and the rivets were set. Then epoxy was generously applied to the front edge to fill in all the ugliness followed by lightly clamping the taped and waxed plywood caul. Then we wait…..
View attachment 100220So far, so good. Four hours later, after an extended lunch, I pulled the clamps and caul off and sanded off everything that wasn’t needed. It turned out pretty good for a part that will never be seen! A bit more sanding and some spray bomb primer and then it was time for an extended dinner.

Next up, brackets connecting the tube to the bumper bolts, brackets from the bumper bracket bolts to the exposed carriage bolts, and reinforcing the center of the pan. Thanks for stopping by.
