Living in the Past
SILVER Star
Have test fitted the gas tank? Not seeing issue with the hold down straps. The brace behind the transmission cover may interfere with the 73-78 style tank where the floor was flat. Believe the 65 bench seat leg leg on the back right side is different than the 71 seat. If you using a 73-78 tank your already dealing adapting the filler neck in that area. I installed 74 bucket seats in my 68 over thirty years ago. Did a small amount of adapting to keep the tool box and cover. Hated to give up a place to lock tools in with the top off.
