Chevy rearend off center, offset leafsprings?

Car: 1953 Pontiac Cheiftain (Canadian)
Issue: Tires sitting to far foward in rear fenders (common issue with old chevys)

Fix: Buy offset Leaf springs
Part: Found part on Eklers 21-261 for 55-57 chevys

Question: Will the 1955-57 offset leafsprings fit a 1953 Pontiac or for that matter a 1954 chevy? When I called Ecklers she simply state no but also said they didn't sell offset springs for any earlier models than 1955.

Or does anyone have a better idea to back the rearend about an inch in order to put bigger wheels on.

Thanks for any help!!

I have used a offset block before. Go here

http://www.chassisengineeringinc.com/page27.html

Look at the bottom of the page and find part # AR-2070

I made mine and did not buy theirs ...
Easy to make ... BUT their catalog photo makes it easier for me to show you ... the solution.

lowering blocks

That's a great idea, I've looked in to it before, but I don't want to lower the back so I guess I could restack the leafsprings to raise it and then install the lowering blocks...hmmmm... I really want to know if the 55-57 offset leafspring will fit the 54 chevy chassis mounts because I'd rather get new leaf springs.

Thanks for the help!

The 55 spring won't fit, too long. Posie's make a spring that will fit with a centered center bolt. Part number is 203A

I went with the Chassis Engineering spring kit on my '53 Chevy. Worked like a charm, I would recommend it.

We're talking about rear leaf springs, right?

I don't know about other cities, but there is a spring shop in Calgary called Standens. They will build leaf springs to your specifications.

Try *your* local spring shop?

Couldn't you just re-drill the spring bolt (mounting) holes in the spring perches and U-bolt plates?

Thanks for all the replies. I'm going to go with making new leafsprings from the local shop. I don't think redrilling them is the correct way to go but would probably work in the short term, I believe the springs are rated to the original center point.

Obviously, you've never tried this. In my younger days, I went through a half dozen bits on just one of the leafs before giving up. After a bit more experience, I came to realize that leaf springs (like any other spring) are highly stressed and not very forgiving to having stress risers induced. Leave the springs alone and find another solution...
