Wow, glad I asked. Too bad I didn't think about buying a steel line when I ordered the tranny cooling lines.
Hopefully I will be able to drive it in and out of the garage this weekend.

The ported vacuum source is typically connected to he vacuum advance for the distributor. On my '71, the TH350 modulator line is appx 1/4-inch steel with rubber connections at each end to ensure a leak-proof seal. I'm sure you can order these from most companies that supply brake/fuel lines. HTH Chuck
