1986 170 mph speedometer

My brother had a 170 MPH speedometer in his '85 GT. He sent his original WORKING 85 mph speedometer out to BBK to get it calibrated and to have the 170 MPH face installed. When he got it back, it was all over the place and he was p***sed! He kept it in there until he found a Ford Motorsport 140 mph speedometer and then he replaced it with that. I believe that BBK is the only manufacturer of those faces but I'm not too sure.
 
That was a sticker i'm pretty sure that BBK just put over the top of your gauge and then recalibrated it. Those weren't very good in my opinion. But i never heard up them being junk as you described. But my 170mph speedo is identical to the Ford Motorsport one. Its not a sticker. Its identical to the 140mph speedo in every way, shape, and form but it goes to 170 instead. Mine also works properly, though, i'm never had the car over 110ish. But i would imagine it works great.

Edit: As for the BBK 170mph stickers. I believe those were available up to atleast last year. I remember seeing them in the Brothers Performance catolog. BBK still may do that as well, i have no idea. Never have checked.
