So what i am looking at doing is possibly converting my truck to a supercab. But i want to keep my existing frame due to major modifications and super camper bed. I am curious where i would need to stretch the frame. Its my understanding that the difference is under the cab not aft cab. What i am needing from you guys is and pictures of the super cab frame side view and top view so i can see where the mounts are.
I wouldnt be considering this except the fact the family is currently 3 and going to be growing to 4 within the next year and i dont want to have to be forced to drive the 6L on camping/hunting trips if i dont have to (too wide and big with chances of scratching the fenders up) I found a cab complete rust free with interior for $200 obo and its got me thinking hard about doing this.
I have a 78 F250 4WD up on blocks. I've dropped the side tank, muffler and heat shield.
You can see the frame and mount locations very well.
I was going to replace the mounts (getting those mount plates off is a real
If you want bottom side pics, I can give you those. but not top side.
One of my thoughts (for my rebuild) was to replace the std cab with a super cab, and ditch the long bed for a short bed.
Once I removed all the stuff (mentioned above) I can 'clearly see' that the frame does not run back from the rear of the
cab to the rear axle in a straight line. There is an 'ever so slight' angle. This is just enough,
that attempting to shorten the frame (by the necessary 9" ) would pose 'major' frame fabrication.
Not something I have the skills nor equipment to deal with. so this plan is a no go.
As for 'stretching', that too may pose you the same issues.
If the frame rails were straight, then this would be a much easier challenge.
Forgot to mention my supercab frame is 2wd that I am converting to 4wd, the mount locations are the same. The only difference in the 2wd and 4wd frames is from the firewall up. Does it matter that my frame I 2wd for your case? I also have pics of a 4wd regular cab frame. Let me know
wow, you must be a super fabricator.
From reading all the posts (here) about guys asking if doing a 2WD to 4WD conversion was possible or easy, the consensious 'I' reached was....
not worth the effort, time or expense (unless you have the tools, equipment and knowledge to do it.)
I"m not saying it can't be done. There are those 'here' wiser and more skilled than I who 'can' and 'have' done this.
I'm just saying... it's a lot of work my man. But, if you're up to the task, let errr rip.
Others 'here on the forum' (and you can search the posts) say... "go find a 4WD frame" and start from there. much easier.
Looking at my own F250 (from the bottom) and looking at 2WD ones I've seen, I'd have to concur. It's a LOT of work to do the conversion.
Last year I found a 1 owner 79 F250 2WD super cab with ALL the bells and whistles. It was beautiful.
This guy was late 80's and was finally letting it go. I thought long a hard about getting it and swapping cabs to my 4WD.
But, in the end, I let it go. I neither had the space nor the equipment, (nor the $$) to take on such a job.
It was (however) fun to think about.

My 2 cents for what it's worth.
Well Idk if you've seen my build thread but I've done a lot if work to this frame already. Ive done a Cummins conversion, 4wd conversion, and trying to keep the super camper special bed but now I'm thinking of doing another change. Idk what's wrong with me sometimes Haha.
But I guess we'd technically be talking about a 2wd frame from the front cab mounts back.
I know everyone I think thought I was kinda crazy when I did the 2wd conversion and I read a ton before I started and in the end I thought to myself, it really can't be all that difficult. Plus I'm a glut ten for punishment so I took the challenge from myself and did it.

Perfect because I'm primarily looking for a super cab 2wd frame to look at. I have (2) 4wd std cab frame out in the barnyard so I'm good there but thank you for the offer. So if you can and its not too much trouble I'd appreciate the pictures.
These aren't pictures but illustrations from the Ford parts catalog.
The first one is the supercab body mounts. Scroll down to see the cross members.
Thank you for the diagrams. I'm thinking about trying to head up north to check out some junk yards around the Chico area and see what I can come up with too. Not many dents around here.
