I know it's a pain...but ABSOLUTELY
keep the fiberglass tub/shower/sink. List it in the Airforums classifieds, someone will want it! It is unfortunate that you aren't more centrally located - it isn't something that would be easily shippable, but someone may want it bad enough to make the trek to pick it up.
Also all the lights, knobs & hardware are "great finds" for someone who is looking for them! We had a '64 before and they hold a special place in my heart! They are pretty unique in that the mid-sixties were a transition period and a lot of hardware, lights & "smalls" were only in use for that single year.
Again, take some photos & list them in the classifieds - they will be greatly appreciated!
Good luck in your move & start of your restoration!
