Teves to Vac-boost conversion - parts needed - write-up to follow

[Brock]

I am about 90% through converting my reatta to a vacuum booster system and installing Olds Aurora brakes. 

I am using a booster and master from a 1989 Riviera. I need the proportioning valves that thread into the Riv master. 

 

GM p/n 8016171  and/or  p/n 8012129

 

anyone have these lying around that they'd like to sell?
