I want to get rid of the gas tank behind the seat in my 68 K20. But I also want to keep the stock spare in the stock location. I want to install right side and left side saddle tanks similar to the design on the late 70's and 80's square body Chevy's. Does anyone know of a company that is building these kits? I know I could have one built for around $800 - $1,000.00 but that's not in my budget. The other question I had is, will a stock gas tank off the square body Chevy fit into a 67-72 frame?
