64 Rear suspension options

What options are there for the rear suspension on my 64? Greg has told me about lowering it but what I want is to lower it & do a mini tub with the stock wheel wells.
I want to widen the stock wheel tubs & keep the stock rear springs.
How big a wheel & tire combo can I go with? What all has to be done here?

You can use that later axle just by moving the spring perches.
With the right offset you can run a 10" wheel under a Slick.
I'll try to get you a pic of my modded rear spring pack.

Thanks Greg! I just got done reading the article you showed me!
I'm kind of thinking about flipping the rear & then cutting it down to fit the widdest wheel & tire combo without moving the springs!

You actualy want to widen it to get the biggest tires, unless you are going to get custom offset rims.
A 73-79 9" will get you 31 spline axles and it will widen the rear making standard rims with deep dishes fit. I think you can run a 335 tire in the stock tubs. there is another +2" inches to be had if you tub it, then your current axle might be the right size.
Find the rims you want, and work form there. 335 is a BIG tire.

Thanks for the help here Dan.
So what I'm understanding here is leave the rear the size it is?
I'm thinking about going with a stock looking steel 15" wheel that is widened.
Also what is a 335 tire? Do you me like a 335/60r15 or what?

Correct. 335mm Width. You can use spacers to help adjust the width/location in the wheel well.

I C'd the frame on mine and put the rear end on top of the springs. Used a rear out of a 75 torino and took out some of the leafs. I would like to put a lincoln IRS in one of my other trucks

I will dig up some pictures but it lowered it a bunch. Would have to say like 6 inches. I have a Fatman mustang II front with a BBF engine

Go to photobucket and open an account (free) and then upload your pictures from your computer onto Photobucket.
Then it is a simple task of copy and paste from Photobucket to a post on here. Lots of us use it. TR

Thanks for the picture. This helps me to visualize what it might look like.
As far as a Jag suspension, I'm not really interested. I want to go with an old skool look that's why I'm wanting to find out about this.

I was out messing around in the shop and measured the height of the bed over the tire and it was about 39" to the top of the bed. when I flipped my rear end I took out most of the short leafs to make it ride smother. Hope this helps

Here's an "in progress" shot of Daryl's flipped axle and notched frame.
I'll ask him to show you the finished product.
