O.K. I need all the help I can get, I have a 66 Safari.. dont know if its a double or twin, wich i guess is my first question.. It is in better shape than alot of those ive read about on here, meaning currently liveable, but much work to go.. My second question is where is the best place to get replacement alluminum paneling for the exterior holes? I have the back and back left missing. Please take time to respond it will be greatly appreciated I need help from those of you who know what your talking...
