Fastback tank install ? Urgh !!!!

I had 3 65 Coronets. 1 500 bigblock that I redid and 2 440 parts cars..I dearly wanted to alter one of the 440s but time and finances got in the way.

if you can do it yourself its cheap, think i have 100 bucks into it lol... 2x 15" length of 2x2 and 1x2( or 3 cant remember) and then 2 lengths of 2x3 for up front.
