1986 GL10 Turbo Distributor and Turbo help

[itb482]

Hello all! 
I have a new to me 1986 GL10 Turbo that I attempt to daily for work. It was working and then it wasn’t (the story of all things great). 
I work in EMS so my mechanical knowledge is pretty 101 level. 
it does while driving and then was dead at the key. I check all of the obvious stuff and tried jumping it. No dice. Had it flat bed towed to the shop we take our cars to and they said that the distributor and corresponding parts needs replaced. The mechanic was a former Porsche/Subaru guy so generally what I’d call reliable. 
the problem is that it’s old and parts are super hard to find. The ones found online didn’t match the ones in the car (rock auto for example). I’ve tried reaching out to a local shop in Salisbury (Higgins) that deal in old Subarus since they often keep old cars on site. They have insisted that they will get to the old cars that might have the part but those cars are buried on their lot and I’ve waited five weeks. I just want my car back and working. It was also suggested to me to start looking for another turbo for replacement. Not critical to the function of the car but would be strongly advised. 
 

where can I find these parts? Does this forum have folks who are selling this stuff? I’m sort of at the end of my rope and don’t want to sell a non functioning car that I know would work with the correct part. 
 

thanks in advance. 
 

 

point of clarity. My Subaru is at my shop- not Higgins.
