I have gathered all the parts and accessories from my late dads 1962 BN7 tri-carb and am now cleaning them up and inspecting...The hardtop and windows are in OK shape...not perfect but OK...I imagine they are original as I don't reacll him ever having them restored...I am wondering if I should put a new headliner in the hardtop or leave it as is? The windows are relatively scratch free but the rubber will need to be replaced at some time.
