I am going to Concord in a couple days, I will ride by and see if they have the doors open for business. They are only about 30 minutes from my place.
They have been around for a long time, I used them once. As I remember it was sleeving a cylinder, been so long I can't remember exactly
ops: I do recall I wasn't happy with them or I would have used them again.
You know the old saying "Screw me once shame on you, screw me twice shame on me".
