I have a 64 F100 4x4 and 63 F250 4x4, can anyone tell me the difference?
I remember about 1900 64 4x4s were sold and 1600? 63s, how many 250s for those years were sold?

Plus, can i get some help deciding this vin?

 

That door tag is for a 1966 F250 2WD. Door might have been swapped and they didn't swap the tag.

Here's the full decode. Like I say, if this doesn't sound right for one of your trucks then the door was probably swapped and the tag wasn't.

F25 = F250-2x4

Y = 352 2V

P = Twin Cities, Minnesota Assembly Plant.

844558 = 1966, assembled April 1966

129" Wheelbase.

B = Caribbean Turquoise

F250 = F250 2WD, 7,500 lbs. GVWR

381: 3 = Medium green crush vinyl and medium green wicker pattern vinyl / 81 = 81A Standard Cab

A = NP435 4-speed

24 = Spicer/Dana 60 Rear Axle / 4.10-1 / Non-Limited Slip / 5,200 lbs. Rear Axle Capacity.

7,500 lbs. Gross Vehicle Weight Rating.

172 net HP @ 4,000 RPM

42 - Fargo, ND - Ford District Sales Office - where the original selling dealer ordered the truck from

Hopefully this comes through OK. I've done the full list before in a table format perfect for a forum and it looked great for a few weeks and then it got scrambled. Here's a portion of that list. From the Standard Catalog of Light-Duty Ford Trucks - 1905-2002. First column is 1963, second column is 1964.


F100 4x4 Chassis & Cab 179 330
4x4 Flareside Pickup 967 802
4x4 Styleside Pickup 2,809 2,922


F250 4x4 Chassis & Cab 348 410
4x4 Flareside Pickup 865 1,028
4x4 Styleside Pickup 1,835 2,232

Enjoy!

Thanks Chad! Very helpful.

I guess it makes sense that a F25 doesn't have to be 4x4, bad assumption on my part. Is the biggest difference between f10/11/25 the axles? Nice to know the F25 had a dana 60 already.

 

Oh, and the door is more a color match thank warranty plate correct. Just curious where it came from. Trucks vin are different, def 4x4s, but the 63 might be a F25, not 100.

 

Yes, axles are 8-lug instead of 5-lug. Wheels were mostly heavier duty. Typically heavier duty choices like the Dana 60 in the rear. Springs were often beefier and/or more leaves and the frames were a greater "modulus" number, which took into account things like metal thickness, girth, depth of channel bends, etc.

And badging. That was about it in 63 and 64.

Series code, first 3 digits of the VIN: F10 = F100 2WD / F11 = F100 4WD / F25 = F250 2WD / F26 = F250 4WD

ALL 1956/72 F250's have a Dana 60 rear axle. Some 1973/84 F250's have a Dana 60 rear axle, some have a Dana 61.1 rear axle.

F100's have 5 lug wheels on a 5.50" bolt circle. F250's have 8 lug wheels on a 6.50" bolt circle.

 

thanks! even more clarification. The 63 is titled/registered as a F25, but is 4x4 (maybe a conversion). But it has 5 lug wheels, so maybe an axle swap as well? Or maybe a wrong title. Either/any way, i'll get em driving and protected from rust. Fun projects, and I didn't overpay for them. Glad I negotiated well. Gonna be drivers, not trailer queens.

 

So I found the VIN stamp on the frame. the 63 is an F11 factory 4x4 (battery is in the cab) with 5 lug wheels. Gonna look into fixing the title.


The more I dig the more I learn, thanks for your help.

 

For '65 and '66, both the F100 and F250 2WD 129" frames had the same modulus; 3.71. The 4WD 129" frames had a slightly higher 4.14 modulus.


The 65/66 short bed 115" 2WD frames had a 2.98 modulus and the '66 4WD short bed frames had a 3.17 modulus. There is no listing for a '65 4WD short bed, so I can only assume one wasn't offered.


The only difference in the 65/66 F100 and F250 frames are the 5097/5098 support brackets riveted to the frame that support the #3 cross member (back cab support). The F100 support brace only supports one side while the U shaped f250 part supports both sides of the cross member.


In '67 they lowered the modulus for the F100 2WD 131" WB to 3.06 while increasing the F250 2WD 131" modulus to 3.89

 

Those are the service replacements that are called out in the MPC - Notice the 1965 is calling out a part number of C6TZ-

They could cover both bases by having one service replacement frame so they didn't have to stock both parts.

I have the 1966 Salesmans facts book and it goes into vastly more detail and all F100 2wheel drive series came with 2.98 frame modulus originally.

Dang, I have to get that book. Thanks for the correction.
