OK, so perhaps ND can help but I'll welcome any feedback.
So I go to the local auto parts recycler (junkyard) this morning just to see what they have and I find a great 1960 F100 Flareside 8 foot and the bed is in excellent condition. However I notice that the side bed panels have a slight flare into the bed whereas my '65 has smooth side bed panels and is the 6 1/2 foot bed. This '60 flareside panels are in much better condition than my current panels so I'm thinking of purchasing the '60 bed. Will this bed bolt up to my 1965 frame? Does the "flare" in the '60 cause any issues?
Thanks for any feedback.

 

The original 1953/56 6 1/2' & 8' Flareside quarter panel (bed side) part numbers were replaced by 1957 part numbers for use as service part replacements.

In 1961, the 1957 part numbers were replaced again. The 1961 part numbers remained the same thru 1972.

F350's with their exclusive 9' Express bed quarter panels were replaced in 1957, the 1957 part numbers remained the same thru 1972.

The 1953/56 tailgates were also replaced in 1957, remained the same thru 1972.

The 1953/56 Flareside fenders were replaced in 1957, remained the same thru 1979.

The 1953/56 front panel part numbers didn't change until 1976.

If Ford says all these parts will interchange, I see no reason why the entire bed couldn't be used.

The 8' mounting holes may be different due to a change in the length of the wheelbase.

 

If your talking about a wheel well intrusion into the bed, it could be an F-250 bed. My 66 F-250 has the intrusion, it is actually caused by the bed being wider, and it is also a taller bed than the F-100. I am shortening the one I have to put on my 65 shorty.

 

The 8' Flareside bed was used on both F100's & F250's. The 6 1/2' Flareside bed was only installed on F100's.

The tailgate of F100's with the 6 1/2' Flareside bed is 49 13/16" wide. The F100/250's 8' bed and F350's 9' Express bed tailgate is 54 13/16" wide.

 

Aren't the F250 fenders different than the F100 as well? Thinner profile?

 

The '60 thru'66 6 1/2' and 8' flaresides are almost completely different beds, the 8' is longer, wider and taller. The same '60 thru '66 8' flareside bed was used on both F 100 and F 250. The difference is the location of the fenders and mounting braces to frame, which is depends on the wheelbase of vehicle.

 

B7C-16312-A Right & B7C-16313-A Left .. 1953/79 F100/350 Flareside Rear Fenders.

B7C-16313-B .. Left Rear Fender with Cut-Out for Spare Tire Clearance: 1953/79 F100 & 1975/79 F150 with 6 1/2' bed.

B7D-16313-B .. Left Rear Fender with Cut-Out for Spare Tire Clearance: 1953/79 F100/250 with 8' bed

 

Thanks all for the great info.

So, based on what I am reading, the 1960 8ft flareside bed will not fit on my 1965 115" wheelbase frame that currently has the 6 1/2ft flareside, correct?

 

For some reason I thought somebody here told me the f250 was bigger than the f-100 last year when I bought the 66. I must have been mistaken.

 

you can get almost all the parts for a 6' bed from mar-k it is the 8' bed that is hard to get parts for


I got parts for my bed from mark, npd, and sacramento vin ford it will take some time I waited for 6 weeks for a crossmember from npd and they raised the price from $45 to $95
its not pretty but you will be able to do it

 

If you're not going to use/buy that bed, I'd be interested

 

I know im Hijacking this thread & sorry but whats the best way to fix the Step part of a flareside cause mine has little holes threw it now but the rest is solid

 

PM me and I will give you the location of the bed.
