Needed: gallon markers, both tubes in the glass, electrical mast and lighting parts, jar rods
I would also consider just trading signs, if no one around me has the parts for my 620 for a project visible or electrics pump, local again
Gallon markers come up on here every once in awhile.
Are you talking about the pump tubes that are inside the cly?
Ron Scoobie has some of the upper electrical parts (and I've got some on order thru him for one I've sold) but some, like the conduit and wire setup to plug it in, you can make your self and you have to wire it all up when you find the parts or take it to a good restoration shop.
You can make the jar rods or have them made. There might be a vendor (like Ron S., Vics 66 or Gas Pump Heaven) that has them pre-made.
