I have a cast rear end housing in a dragster. It is made by Boulton-Rosser from Tishomingo,OKla. It is in a solid car. Does anyone know anything them? It might be done before aluminum housing were popular. I don't know how to post pictures here. Thanks for looking

yes they were a chassis builder at the location you mentioned. I'm not sure if they are still in business or not.

My first car was a 235" Boulton with their front suspension. Car worked well for me and the original guy that had it built. It had been some 4.40's and sub .9's 60 foots with no issues.

Last I heard my old car had been updated by Diamond and was either in Tenn or Ohio now and the chassis was orange now over the black when I had it.

My first store baught car was a Bolton hard tail. Bob Sr. told me once who was casting those rearend housing for them, but I don't remember who that was. Bob Sr. pass some time ago, and Bod Jr. continued to build cars. Not sure if he still does. Bob Sr. was into front engines dragesters and worked with Neil & Parks. They may be able to provide some
information.
