Any ideas on interior for a Low Sedan

Just got my Caddy powered Sedan to move, now wondering about what to do with the inside.. There is a plywood floor... Im going to leave the body the way it is... Any ideas.... This car is a rocket... and yes all six carbs work...

 

Hmmmmm... how about a pair of egg crates and some rope for the seat belt

 

early (65-66) Mustang seats are pretty low. Thin cushions. Brit sports car? Jap Sports car.

 

Where i found this pic it said they may be old pub seats or bar stools.

 

I found some old willys jeep seat I think are going to work.. How about the door panels?

 

I used bug eye sprite seats in my A coupe

 

The bar stools look really good!
