leg room

I have a fiberglass 23 bucket T.I need some more leg room. Would changing from bucket seats to a bench seat,a new steering column,it has a late model Chevy tilt in it , or a spoon gas pedal ,it has a regular accelerator pedal . achieve this ,or? Thanks.

The only way I am aware off adding room is to lengthen the body.

Thanks for the information.

How thick are the seat back cushions?

You really don't need much padding here, but you do need a lumbar support and an angled seat back.

A 2" thick upholstered firm foam pad will do it.
Upholstery shops carry foams in different thicknesses and densities.

Making your own seat & back bases from plywood is easily done.
And upholstery shops will have no problems padding and upholstering the plywood backs.

Thank you very much for the information. I appreciate it.
