Can anybody tell me the 1980-1986 F100/F150 Wheel Bolt Pattern

I believe the 80 and 81 F-100 Had the smaller car lug pattern of 5 x 4.5

My old 81 flareside was 5 x 4.5. Mine was an F-100.

Flareside? Is that the same thing as a KirbyMan Stepside?

generally 5 on 5.5" (same as old Jeeps and dodges)

light duty trucks with power brakes should have 5 on 4.5" (same as Ranger, explorer, Newer Jeeps, and most Ford cars)

My '81 f150 is 5x5.5

So I can use either 5"x4.5" or 5"x5.5" Wheel Bolt Pattern

no, you have to match what your truck has. measure from center to center of 2 studs directly across from each other

Technically, it's not center to center on 5 lugs. You measure from the edge of one stud, skip one and measure to the center of the next one.
Even numbered patterns are measured center to center.

If I remember correctly, on the F100's with factory power brakes, it was 5 on 4.5" circle. F100's with manual brakes were 5 on 5.5" circle. I think (may be wrong) all F150's in the '80-'86 range were 5 on 5.5"

Someone can correct me if I got that wrong.

f100jim is 100% dead on. Power brake F100's have oddball brakes, rotors, etc, Manual brake trucks have standard F150 stuff.

So it depends on the the year,model,& type of brakes then:
'80-'81 F100 :5 on 5.5" (manual brakes)
'82-'86 F150 :5 on 4.5" (factory power brakes)
Correct or vice versa

Vise versa.
And the 80-81 F-150's had 5x5.5 as well.
