[urq] Brake Booster

[MikeDes156 at aol.com]

OK, I've replaced everything that has to do with the brakes, except for the 
Brake Booster. Calipers, G60's up front, 4000Q's in the rear, master cylinder, 
SS lines, brake bias unit, the bomb and the unit under the bomb. I realize 
that they are NLA, but the ETKA shows two part numbers for the Brake Booster, 
857612107A and 859612107. I was told that the 107A unit is available. Will that 
work in my early build 83 #459? I've replaced the parts a a preventative 
measure, and the brakes work ok, but they feel a bit spongey even after bleeding and 
replacing the brake fluid. What tells me that the Booster could be on it's 
way out is that I see a small amount of ATF leaking on the screw/stop located on 
the bottom of the booster. Any suggestions?
