Yup...no upholstery other than the seat...no carpeting either. Everything not painted will be covered with the tinted bed liner. The plan is to make the entire seat removable by pulling hinge pins, and/or making the seat cushions velcro in for easy removal. A few reasons for this route...
The first being that this thing is likely to be outside all the time...no garage, only a car cover when parked...no top, only eventually a tonneau cover when out and about. Our property is adjacent to a large wooded ravine, so we have a large variety of varmints that would make short work of converting upholstery to nesting material. No worries about wet upholstery.
Next, though this car will be built from a T-Bucket body, frame, and many parts, it's not going to be built T-Bucket style. It's going to be built in a post war T Modified/Track roadster style...a race car. Not to many race cars with upholstery.
Finally it's simply a matter of keeping it simple and low budget.
