Does anyone make a plate or spacer that mounts between the front leaf hanger and the frame to move the axle back a small amount? Im trying to create a little more space at the front of the wheelwell for a tall tire.

Thanks
 
Always liked the idea of doing that, helps to center the rear wheels in the wheel openings along with the extra room at the front edge.

Find a metal fabricator and have them make you up a couple 3/8" thick steel plates with the proper mounting holes in them. Can use cardboard as a template so they can make the parts for you.

Great idea. Are the studs long enough for 3/8 plate?

Simply place a spacer between the spring hanger and the chassis to move the axle housing back on that side of the vehicle. This can be used to move the axle housing into proper alignment, or it can be used to create additional rear steer for circle track applications.
 
Going to be real close for the length on the studs with the 3/8" plates. Would be a good idea to use New 1" or even 1 1/4" long studs. Takes a little more work to swap out the studs, but this is what's pushing the car around and you want it to be strong. Can use the proper washer stack with the new studs too.
 
Using the spacers does that require shorter springs ? Or does the shackles make up the difference? (Sliding them back)
 
Dartfreak75, it just swings the shackle a tad when adding the spacer plate. Don't need the shorter spring like Roy says.
 
Does this leave enough driveshaft spline on the tail shaft of the trans? I guess 3/8" isn't that much
 
I'm not diggin my MP suspension book out, cause I don't give that much of a crap anymore, but there's "something" in there about the intentional short segment in the A body. I don't remember "what" but they talk about it being an advantage somehow. Maybe if my give a crap o meter goes up a little more, I'll dig it out, but probably not.
 
Moving the axle to the rear dont affect the spring length. It all moves....

@RustyRatRod

I moved mine almost an inch to the rear.
But I centered my tire and moved the springs under the frame on sliders, with mini tubs.

Did you move the rear shackle any at all?
You put rear sliders on it didn't you?

I didn't say it did. Read what I wrote again.
 
Yeah. I moved it into the scrap bin and I installed spring slides.

Better traction and lowerd the *** end, so it was a win win.

And I got a fair bit of room for more tire but I don't wanna get into the big boy tire size.

If I ever do it again I would run the mini tubs up to the package tray and set the car on the ground.

I had some 1/2 inch aluminum plate that I cut to fit and drilled to fit. Bought longer grade 8 bolts.

Althou, I kinda wanna know. What were you using 1/2 in aluminum plate for that you just had it laying around?

Although I did not have to move mine very far, about a 1/4" inch, to square up the rear axle to the car. I just took a die grinder to the axles mounting hole and took out what I needed to get the axle square.
