Width of 55-57 Chevy frame at center link?

[Mutt's37Buick]

I'm considering using a power steering kit designed for the 55-57 Chevy on my 37 Buick.
1) Does anyone have a 55-57 Chevy they could measure for me?
2) I'm looking for the distance between the mount surfaces for of steering gear box and the ilder arm bracket. See attached instructions.
Thanks

Here is a detailed 55 chevy frame drawing. You might have to save this picture into your pictures and enlarge it 300% to read all the numbers though.

That might be too blurry to read, so here is where I found that picture......much easier to enlarge it on there.

If all else fails, let me know and I can measure a 55 for you.
