Model T Fords were designed when people, as a rule, were smaller and auto designs were still evolving from horse drawn buggies. So, the seating was not designed for people to sit in but rather to sit on the roadster. Next time you get a chance take a look at an original open body Model T. The bottom of the seat is quite high and the seat back is abreviated. If you want to get down inside a Model T roadster being a small double amputee helps. But for most of us the only way is a stretched body.

A number of manufactures make them. I like the Zipper modified bucket. About 2K. Polyform has a good reputation. I think their prices are a tad high. But being close has it's advantages. I'd call them and ask them about coming over to test fit one of there bodies. They may not have one on hand but ask them to call you when they do.

If you bought all five of the California Custom Roadsters plans you will have drawings for all of the suspension parts. Your truck axle is most likely too heavy and does not have the "right" spring configuration. Make the axle in the plans and use the brakes on a set of 37-48 spindles.

Depending on what body you select the CCR frame plans may require some adaptation. But that is reasonableyeasy to do.

I like your plan. The objective for anyone building their first rod should be getting it roadworthy in a reasonable period of time. Concentrate on workmanship. A good concept properly executed will earn the respect of seasoned rodders even if it does not sport a lot of fancy paint and chromed components. There is nothing wrong with low buck if your standards are high. Good welds, square cuts, nice proprtions, attention to detail, etc are what it is all about.
