Looking for distributor for '91 80q

[Robert Rossato]

This is for a friends '91 80q (I think I noted it as a 1990 last time) that kept stalling after about 5-6 seconds.  To recap from a few weeks ago, it will start and run fine when dead cold in the morning, but after it warms up it will shut down.  Once warm you can start it immediately, but always shuts down in 5-6 seconds.  Very consistent.  No amount of throttle manipulation would keep it running.  

He has installed a new Fuel Pump as old one was noisy anyway.  No change.
New fuel filter. No change.
New cap & rotor. No change.

This weekend we borrowed a distributor from an '85 Coupe and swapped it.  Rigged up a line to the vacuum advance, which isn't present on the NG motor, and this seemed to do the trick.  It would seem the problem is with the hall sensor. 

So, does anyone have a spare distributor available for sale?
