Finding a glass top for any pump is expensive. Most are worth more than a restored pump w/ globe.
T-way on this site has the largest collection of ERIE 70/71's that I know of.
Jack Sim has a web site full of brochures for sale of most pumps & equipment found around old stations.
Joe Yocom can restore or help with the VR/CLOCK mech.
T-way & myself can help with custom decals/adv. glass
