Does any one know where I can find a new, not used rear transmission crossmember for my 1966 f-250 4x4. I looked everywhere, to find out that they only go up to 1964, Or are they the same in 1964 as the 1966. I also have a 390 v-8 in it with a brownie trans. Appently the person who owned this truck was a welder and made it out of an old leaf spring. Can anyone help . Joe

 

I could stand corrected, but I believe your truck uses the same chassis as the 64. This is for 4X4 only.

C4TZ-5025-A .. Crossmember-rivets to frame rails / Obsolete

No FoMoCo Dealer or obsolete parts vendor has any.

Applications: 1961/65 F100/250 4WD / 1966 F250 4WD / 1961/66 F350/750.

Note: 1966 F100 4WD is not the same, is referred to as a 'rear engine support' and bolts in. There's 2 types, depending on engine size.

 

Check to see if the frame your body is on is actually a 66. Look for a VIN just aft of the passenger shock tower or under the cab on the top of the rail.

On the rear of the tailshaft on transmission, That should be rivited in instead of bolt to the frame. On a f-250 4x4 model.

 

Wildfoot6 do you have any pictures of the setup you currently have in your 4x4. Sitting here thinking about what you are saying it is hard to believe someone used a leafspring as the rear motor mount in a 4x4. The frame crossmember that NumberDummy is refering to is for the bellhousing with ears on it. They are in fact the rear motor mounts in the 61-66 f250 4x4s is that what you have?

 

Again on a 66 f250 4x4 your rear motor mounts are not on the tail section of the trans. The bell housing has two ears that rest on the frame section. If yours is on the tail section of the trans it is something other that 61-66 F250
4x4. Or someone has a different than stock bellhousing in the truck. If you can post up some pics it might help.

 

The c/member rivets to the frame rails. The b/housing has 'ears' on it, the bottom side of the ears is threaded.

Right/Left u-shaped rectangular steel/rubber trans insulators fit between the ears and the c/member.

Below the c/member are R/L rubber donut type insulators. Bolts pass thru the donuts, thru steel pipes, then thread into the b/housing ears, tying the whole tamale together.

[ATTACH][ATTACH][/ATTACH][/ATTACH] Here are the pictures, of the crossmember, and the truck.

 

Frankenstein monster, has more than just a mickey-mouse trans mount installed.

This type of Styleside bed isn't original to the truck, was used on 1964/66 F100/250 2WD's & 1966 F100 4WD's.

1961/65 F100/250 4WD's and 1966 F250 4WD's used the 1957/60 Styleside bed, called the 'wrong bed' because the body lines don't match up.

Looks to me that this truck has been cobbled together from parts used on other vehicles. It looks nice, but...

 

Who is Frankenstien monster, And are you saying my bed isnt orginal to the truck. NumberDummy.

 

That's exactly what I'm saying....this type of Styleside bed was not used on any 1964/66 F250 4WD, 1964/65 F100 4WD. These trucks used the 1957/60 Styleside bed.

The only 4WD that used it were 1966 F100 4WD's...that have coil spring front suspension and a "factory lift" that allowed the rear wheels to clear this type of Styleside beds wheel wells.

When you open the doors, does your '66 F250 4WD have a step or is the floor flat? If flat, the cab is not original to the truck.

The cab used on 1961/64 F100/250 2WD's, 1961/65 F100/250 4WD's, 1966 F250 4WD's and 1961/66 F350/750's has a step when the door is opened.

1964/66 F100/250 2WD's, 1966 F100 4WD's do not have a step, the floor pan is as flat as Kansas when the doors are opened.

A "Frankenstein monster" is a truck that has been cobbled together with parts from other vehicles.

 

When I open the door I have a step. From what I understand from the one who owned the truck it came from California, It was driven here. It has factory leaf spring front and back. The only thing that isnt orginal to the truck is the engine, and now you said the bed. So I still need that part. So will the 1964 part work on it for that crossmember.

 

Well said Bill. I agree the truck looks well done. I actually like the newer styleside box as it keeps the body lines flowing. Wildfoot6 if you look at my builds or my profile pick you see the long wrong box that should be on your truck. Also try Carolina Classics I think I have seen them selling a bolt in trans crossmember. Probably the trans is not original either probably out of a newer truck. Is there a crossmember just ahead of the trans in your truck with 2 holes on it? This crossmember would angle down from the frame with 2 holes on either side about midway down the angled surface. If so that is where the original bellhousing Numberdummy talked about would mount.

 

The rubber insulators (upper/lower), bolts and etc are the same: 1961/64 F100/250 2WD/4WD / 1961/66 F350 / 1965 F100/250 4WD / 1966 F250 4WD.

You will need the crossmember and the correct 1965/66 "eared" bellhousing to install these parts.

There are several different bellhousings. What size is the swapped engine? If it's not an FE or a 240/300 I-6, don't expect to find one that will work, because there isn't one.

There are several other things that are not original: The rear engine mounting, the outside mirrors are off a 1973/79 F100/350, someone bent the arms so the mirror heads would sit level.

The anodized aluminum grille was only available with Custom Cabs. Your truck does not have stainless w/shield reveal mouldings, so it's a Standard Cab.

The chrome front bumper was available on both Standard/Custom Cabs.

CA vehicles: If the DSO code on the Warranty Plate is 71 or 72, the truck was sold new in CA. Anything else, it wasn't.

People join FTE to get correct info. Many get the info after they have bought a truck and so, when they find out things are in-correct, many are not pleased.

Research first, buy second, then you won't end up with a Frankenstein monster or a "pig-in-a-poke." I've owned 337 vehicles since 1956 (83 Ford products, 60 Packards and other assorted old rolling piles of misery).

I never bought a Frankenstein monster or a pig-in-a-poke, because I knew what I was buying. I have over 3,000 books on auto history in this menagerie and have read every one of them.

I also subscribe to Hemmings Motor News, Hemmings Classic Car (formerly Special Interest Autos), Automotive News and myriad car club magazines. If you're gonna be in this hobby, you gotta be well informed.

Ditto firearms and other assorted collectables.
