[urq] UrQ brake booster/servo

Hi Eric,

Thanks for the great info about the brake booster. You mentioned that you 
have a document that you were working on about the differences between the two 
brake boosters. May I have a copy of that?

Also, I'll assume that the later P/N is the aluminum booster (857 612 107 A) 
compared to the earlier one (857 612 107). My question is, are these two 
boosters interchangeable? The reason I ask is I was offered your BMW replacement 
and want to know what (if any) mods needed to be done in order to make it work. 
You said that the rod that goes to the brake pedal is shorter, can this be 
removed and replaced with the correct one from the original booster?

Thanks again,

Jim Furdyn
