There were so many posts with pictures on the subject last year I did it with out a kit. It was easier that I thought it would be. Some even posted the measurements. I had them in word pad but must have deleted them Cuz they are gone.

If your doing it for tire clearance the wheel tubs are almost in line with the outside of the rear springs. The tubs will have to be widened also.

I have the drawings if you have the skill or someone that can make the parts.
Life is not the way it's supposed to be. It's the
way it is. The way you cope with it, is what makes
the difference.

correct me if I am wrong or not but I heard that as long as your going to be (like me) running airshocks in the backend) I am not going to lower the backend at all on my 57. I am moving the springs inside of the framerails. I was told as long as im ot lowering the car any I can run a wider tire under the car without widenign the fenderwells. I still might end up widening them and mini tubbing the car anyways. I am going to be running a 13inch wide tire. Please let me knwo if i need to mini tub the car or not.
thanks,
Jimmy

I made my own. a frend let me look at his and mesure it. you will need to find bushings for the rear part so you know what size of pipe to use.The pockets are made from 3
" x 5" rectangler tube 3/16" it is easy if you have one to study. GOOD LUCK

Jimmy,

For years a popular thing was swapping the leaf springs and hangers side to side so the springs could be mounted inside the frame rails. I know people who di this to their Classics in the early 1970s.

It means removing the spare tire well.

You should be able to get 255 or possibly a 275 size tire inside a stock '57 quarter without mini-tubs or whacking the quarter panels open.

You also need to realize a LOT of this depends on backspacing of the wheels used that there.

Without doing any minitubs or moving the springs you can fit a 274x60x15" tire with a 4 1/2" backspace,if you put in a pocket kit and mini tubs you can really go wild,both the minitub and spring move must be done,if you do just one then its pretty much meaningless

a few things here.. I'd like his questions answered about whether there are any drawbacks.

I've currently got 255/60/15 with 4.5 backspacing on 15x8 wheels on my stock with stock rear, no minitub, and no relocation of springs. I've done this on two cars, 57, and 56.

I can tell you clearly that the springs are the limitation to some extent. I've heard of folks on here that have gotten 275's even 295's on their car by relocating the springs without mini tubbing. This contradicts some of what you folks are saying, any clarifying of this?

Hey busyguy,
I have 295s on my 56 without tubs, but the rear end (ford 9") has been narrowed, and springs moved inside the frame. They are REALLY tight but are not rubbing. I plan on tubing the rear to get bigger tires and to lower her down. Hope this helps.

275x60 15x8 4 1/2 backspace no tubs no spring relocation,I dont think a 295 will fit in mine,maybe with a spring move and a 5" backspace it might go,a spring move without tubs will only give you an extra 3/4"

I would think that getting a 295 tire under the car without tubbing would be very tight on the ones that could and it wouldn't even work on some cars, but you'd almost certainly have to move the springs. Some won't even take a 275 with the stock springs, some will.

Another thing that hasn't been mentioned is that if you do a pocket kit and want tailpipes out to the bumper, you need to get rid of the spare tire well and center the gas tank.

The biggest drawback I can think of to a pocket kit is that it would be a nasty dirty job cutting and welding the pockets on a car that has the body on the frame. This is so much easier to do with the body off, I'm sure glad mine was. Of course that goes for any frame/suspension mod.

I have 275/60 15 BFG's on my wagon with an early Nova 8.2" rear end which is 57.75" wide. The wheels have a 3.75" backspacing, 8.5" wide, and the tire was very close to the side of the spring. With a .250" spacer everything fits great. I am in the process of building another stock frame with Earle Williams Motor, Trans, and rear shock mounts, along with a spring pocket kit.I picked up an early ford wagon 9" rear end which is 57.25" wide and I think that with the same wheel I should be able to fit a 295/50 15.

I've got a 245/60 on the back of my pink/white Hardtop with a 4" back spacing Cragar SS wheel and could get away with running a 255 tire.
