I have a 1967 f100 I am restoring, well making a few modifications on, not restoring to original. We are putting a 1975 twin i bean on it in order to have disk brakes. I am wanting to put a set of wheels on it that need a 5 on 4.5 bolt pattern. I am not even sure if they make that rotor that will fit on the spindle on the 75 i beam. Does anyone know?

Thanks

 

67fordok Welcome to FTE & the Bumpside forum

All Ford half ton trucks from about 57 to 97 use 5 on 5.5.

Number dummy will post if there are exceptions.

Thanks for the welcome.
You are correct about the 5 on 5.5. Pre-57 had 5 on 4.5 and the wheels I am wanting to use need that size. I am wondering if the ID on the caliper/hub is the same thus allowing me to put new races and bearings in and put them on the 75 axle.

 

The F100 used the 5x4.5 bolt pattern for a few years around the late 70s and early 80s.
A quick look at an 80 F100 found a set of rotors for one with 4600lb GVW that was the small pattern. That vehicle also shows the same wheel bearings as the 75 F150, so there is a possibility it may work out.
If you ask nicely at a competent parts store they may let you compare the rotors from a 75 F150 and an 80 F100 to see if it'll work. Just make sure they aren't busy then.

 

Some 1980/83 F100's have 5 lug wheels on a 4.50" bolt circle, the only F100's to have this pattern / Some 1980/83 F100's have 5 lug wheels on a 5.50" bolt circle.
5 lug wheels on a 5.50" bolt circle:

1940/47 Commercial (1/2 ton trucks) / 1940/48 Ford/Mercury/Lincoln Passenger Cars / 1948/52 F1 / 1953/79 F100 / 1966/96 Bronco / 1969/74 E200 / 1975/96 F150 / 1975/2013 E100/150 / Some 1980/83 F100.

F150's went to metric wheels in 1997, but no Econoline of any year has metric wheels.

1980/83 F100's with 4.50" (GWV's less than 5,000 lbs.) use different rotors than 1980/83 F100 (and F150) with 5.50" bolt circle (5,000 lbs. GVW). Wheel bearings are the same F100/150, but front grease seals are not.

The F100's rear brakes with 4.50" are 10" x 2 1/2." Rear brakes on 1968/79 F100's, 1975/96 F150's and 1980/83 F100 with 5.50" are 11" x 2 1/4."

The rotors used on 1980/83 F100's with 4.50" will not clear the calipers of like passenger cars with 4.50" pattern.

Ford advertised 1980/83 F100's as a "Light Truck." Some have "Swiss Cheese" frames, different brakes/suspension/shocks than like F150's. No 4WD or Super Cabs were available.

Circa 1983: Local 'hot rod' shop installed F100 4.50" disc brakes on a '33 Ford, then went to install 4.50" Mustang styled wheels...wouldn't clear the calipers. Came to the parts counter cryin' the blues.

 

I was thinking the speedway magazine showed a 5 on 4.5 for 56 back to (cant remember what year it was). Anyhow, it looks as though an 80s model may work. Ill check in to it. Thanks.

 

According to speedway, 48-56 had 5 on 4.5, 5 on 4.75 and 5 on 5.5. I do not think they will fit on the 75 spindles however, at least again according to speedway.

 

I don't give a rats behind what Speedway claims. There's no 4.75" bolt pattern used on any Ford truck, including 1957/79 Ranchero's.

TAAA-1007-B 5 lug 5.50" 15" wheel-1955/66 F100. B4C-1015-A 5 lug 5.50" 16" wheel-1948/52 F1, 1953/66 F100. 8A-1015-C 16" 4.50" wheel-1949/56 Ford passenger cars except sedan delivery and station wagons.

The F1/F100 wheels are 'innies' so called because the hubcap snaps onto tabs located on the inside of the wheels center section. 1966 was the last year they were available.

 

Must be a custom thing they are doing, who knows. I wasnt worried about that size, just quoting them.
