Does anyone have a photo or drawing of how the front fenders attach to the running boards? I tried a search but could not find anything. Got new fiberglass front fenders. Have to drill holes for attaching running boards

 

Stock boards just bolted to the fender, two bolts at the front IIRC. The fenders and boards get all torn up there from the movement of the two pieces (boards are mounted on the frame, fender is isolated from the frame). I also have glass fenders (and boards) so I am going to make a 1/2" hole thru both and put a rubber grommet or sleeve, then use O/S washers on both sides. It will clamp them together but allow some movement. I will also put some anti-squeak or similar between the board and fender.

 

thanks, Albuq f1
I thought were do little sheetmetal plates about 4"x5" that went on the front.

 

I'm not sure what year truck you're talking about but the 53-56 had one bolt at the front and two at the back. The front bolt has a rubber spacer about 3/4 inch thick. I'm not at all sure what the F1 's had, if it was two bolts I'd imagine the reason they went with one was because of the cracking it did to the front fenders.

 

sorry forgot to say the truck is a 48 f1

 

Hi there!

Here is a picture of the "Front Fender Extension Panel" (or words to that effect) that you mentioned. It bolts to the upper edge of the running board and to the bottom inside edge of the fender.

As you can see there are two bolt holes in the running board. The fender has a very thick spongy welt between it and the cowl side, and is bolted to the running board through the two holes you can see in the picture - with carraige bolts - with the heads (square holes) in the fenders. Normally the bolting process helps "mold" the fender to its "correct" final shape in the curve of the running board.

For your Fiberglass fenders use regular bolts with fender washers. And you might ask Ross how he protects the backs of his glass fenders from rocks and road trash thrown up from the tires.

Having removed a set of fenders where the rears were absolutely destroyed, I would install a thin rubber cushion between the two or some type of mastic/caulking to help distribute the area of the holding surface beyond the bolt holes. Especially if you are bolting glass fenders to metal boards. But, I'd get with Ross on that to for the last word. I have pictures of the old fatigued fenders if you want to see them. Here's my newly installed extension panels:




I have a full front tilt and can get to this easily if you need other pictures

Good luck,
Julie

How do you protect backs of fenders from rocks ,etc.?

Julie more pictures would help. The dark background makes it hard to see just how the "extender " is mounted

 

I'll get a few tomorrow when it's light outside. The dark background you are seeing is the running board primed in flat black. Mounting this thing is very simple. The one bolt you see on the top of the extender is bolted through a hole in the top of the running board "back edge."

The two holes facing outward on the extender bolt directly to the edge of the fender. Then the lower back edge of the fender bolts to the front edge of the running board through the two holes. Maybe this drawing will help:

This is 51/52 but the backs are exactly the same. 16040/41 are the extension panels. 16068 is the fender welt I mentioned.

I'll get those pictures for you tomorrow.

Happy New Year,
Julie

 

I put 3 coats of bedliner on mine and hope it does ok. It is very tough.
