Slant Six Roadster Build
I built the seat frame out of some wood then upholstered it in waterproof canvas. I used 4" foam and cut holes in the seat base with added webbing to help make it better for longer drives. Still trying to figure out how I will do the seat back and side panels. I thought about aluminum for the sides but was worried it may get too hot since there is no roof but it probably wouldn't be too bad since I would plan to leave it raw. My other option I may go with is to use some waterproof canvas that matches the tan in the seat.
The seat hinges forward for storage and electrical access. Still need to make a hinging cover for the master cylinder to replace the temporary brown wood scrap. I built the battery box out of a street sign and pop riveted the sides together this hangs the battery under the car to help save space. I didn't have a hinge on hand so I made one out of more street sign material and used the old VA license plate for the lid. Under the black cover to the right is a large continuous relay that powers a separate fuse panel so i didn't have to run all the power through the key switch. The key switch supplies a small amount of power to turn the relay on which sends power to most everything else. If I have room I'm going to mount a small fire extinguisher on the front panel under the drivers seat.
The dash is just a sheet of plywood with a metal lip I added to the top. Pretty basic but it does have a GPS speedo and the trim around it is fuel cap trim from a Hudson I found in the woods. Going to make a panel to cover the fuse panel access.
