The Stovebolt Site Forums The Parking Lot Big Bolts Fenders ? Just How bbbiiigg

Can Any of you big guys tell me just how much wider the fenders are on these big rigs? compared to a 57tf and how would they mate up at the cab. I read that they are the same length And do-able.


But I'm 6'4" and Wife 5' And she's deffintly do able but they say we look goofy together



I Ramble on because I cant sleep and to broke to pay attention.

57ExtCab,

The 1955/56 1-1/2 & 2 ton TF fenders are about 39" wide measured across the bottom. The 1957 1-1/2 & 2 ton fenders are about 42" wide measured across the bottom. The reason they are different is in 57 Chevrolet moved the front axle 2-1/2" forward to accomadate the larger tires that were now available and to keep then from rubbing the cab on turns.

The FT trucks all use the same hood so the front to back measurement will be the same. I'm not sure what you need to do about the grille...

Hope this helps.

Thanks Mike Would you happen to know what the track width is on those bigger Trucks. I hit up your web page"Mikes Garage" And glad I did because a picture is worth a thousand words I was real curious what they looked like at the fender -cab Conection. On that fire truck it looks like it sticks out a little Thus a running board. Is this the 42" fender and the 6400 it looked flush with cab. I guess what I need to know is what the outside to outside measurement is or just maybe track width. I'm considering using a 88 chassis beneath a 57- 1/2 ton and thought that these wider fenders would give me some added width. I'v read where a another guy was going to use these wider fenders and cut and weld the smaller outside to these to get the uniformed look frt fender and back Quarter openings the same. I guess some of us will do or in my case diffently consider alot of things specially if we got it laying around. Do you sell any of these fenders or know who does. Are these cabs the same as the lighter trucks?
Thanks alot and any further help is greatly appreciated !!!!!

Gary.

Gary,

I didn't mention the 2-1/2 ton fenders in my other post because they really won't look right on a small truck. These large fenders were stock on the 8000 and 10000 Series trucks. They were designed to be used with a fender extension that allows the fender heal to sweep down and bolt to the running board. My fire engine is a 10000 series with these fenders. The width across the front fenders is 84" and the center to center track of the front tires is about 67".

The medium duty trucks (4000 & 6000 series) have the fenders that look more like a large opening pickup fender. The heal of the fender curves down and meets the rocker molding naturally. The width across the front fenders on these fenders 78.75" and the center to center track of the front tires is about 63".

The width across the light duty front fenders is about 73.75" and the center to center track of the front tires is about 60.5".

One other measurement I can help with is the fire wall to center of the front axle. Hold a straight edge vertically against the fire wall and measure to the center of the axle. The 3000 series is 15.75" for 1955/59, the 4000/6000 series is 10.75" for 1955/56 & 13.25 for 1957 and the 8000/10000 series is 13.25" for 1955/59. With this info it looks like you would want to look for the 1957 fenders as they will have the closest wheel opening to axle center as your stock 3000 series truck.

I don't have any fenders for sale at this time. They are on ebay from time to time...not hard to find.

Yes, all cabs are the same size, the only differences were to the transmission opening size in the floor.

Hope this helps...

Thanks Mike
With these numbers I can go back to the shop and do some Think in. Have you ever heard of guys doing this b4. (puting these bigger fenders on these smaller trucks.)I read some other post on a different thread where they were talking about checking into this idea and cut and weld outside of smaller fender in place of the bigger opening thus getting widder fender with same profile as back opening. I guess you would want to widden your bed and tailgate too.
I measured my Donor chassis (88 1 ton) We measured the outside to outside of frt sidewalls and got @73". I'm just trying to make sure I can use this chassis b4 I pull sheatmetal off. Because it be a good trade to somebody that could use a decent driver.
Not to sound lazy about just pullin it apart and then actually setting my frt end on and see what I got. The thing is,is that I fell 32' off a roof to concrete sidewalk a year ago.I think it was that sudden stop that got me. And I'm finding it difficult to get up and down off floor.
Got a rotisserie and 2post lift on the Things I need list. Just below MONEY. I guess 1 thing at a time. Just happy I got my Health.and still able to walk well sort of.

Thanks again/ Gary

Gary,

I have seen where a guy modified the medium duty fenders by welding in the light duty openings to get the "look" he wanted.

I can relate to your fall...I had an extension ladder slide out at the bottom dropping me 16'. The best way to discribe it...I did a belly flop on a concrete floor while on the ladder.
