TR7 Vac Retard Unit

["Kurt Oblinger" <Kurt_Oblinger_at_AWP450@mail.hq.faa.gov>]

The vac retard unit on my '80 TR7 (Ca. fuel injection) has gone to sieve mode.
Nobody even lists the late Delco electronic distributors. I have one shop that 
says it can send it to a rebuilder for a visual cross reference.

Does any one have a source or a cross reference to an available part? The part
no. on the vac. unit is 9977146  6-7. VIN no. on the car is 401608.

Thanks,
