Don,

If I was going directly down into the doors for the side curtain rod, I'd knock out a machined aluminum piece to take the wear.
A little epoxy on the underside after the paint's on would retain the aluminum sleeve to the glass door with no problems.

I've had very good luck with JB Weld in a number of applications and this would work very well here.

Not sure about the 28-29's, but the 30-31's have two different height windshields.
Same with the chopped versions.
You should be able to get the measurements from a Speedway catalog.

If you're using stock top irons and chopping them, you might try to get some measurements from an aftermarket set of chopped irons or from a stock set of irons chopped.

Chopped properly, they fold up just like stock.

Not sure if it can be done on a 29, but the 31's can be retro-fit with 32 windshield posts.
I've done that with my 31 roadster and it looks nicer (imho) than the A posts.
Along with that, we have the windshield pieces cut out and the lower windshield frame rolled to match the A body.

What makes this windshield different is that it's constructed from 1/2 x 1" rectangular tubing similar to the 32's rectangular in cross-section windshield frame.

A little nicer look than using the typical round tubing found on A frames. Imho anyway.

Not trying to make the 31 on 32 rails roadster into a Deuce, but doing a few different things is going a long way toward making it a one of a kind car.

You can go here and read about the windshield posts.

They're mentioned in the last post I did in this article.
Earlier post photos show the windshield posts on the car.

I'm known as C9 on the HAMB site.
