1966 mgb
I am in the process of restoring a 1966 MGB convertable. Have rebuilt the head and transmission. Starting on brakes. I note there appears to be two different master cylinder repair kits and and indication that one type has some kind of ring grooves. I have looked at the MC on the car and pulled the piston but it does not appear to be anything like types described. Also have not been able to find tach connections which I assume is mechcanical. I am a bit large to fit underneath the dash to look at rear of tach nor do I see a connection on the transmission. Any help appreciated

Re: 1966 mgb
The mc kit with "ring grooves" is for a tandem mc, a snap ring goes in the groove to prevent piston over-travel. If the tach is mechanical type it would have a cable drive off the side of the distributor to rear of tach. But I think that year was a 12v tach? if so then it picks-up current from the neg. side of coil i beleive a white wire w/black tracer. hopfully i helped

Re: 1966 mgb
Mechanical tachs were on all 3 main engines and used up until late 1964. After that, all were electronic! Hope this helps. PJ

Re: 1966 mgb
I forgot to mention that the tach drive was off of the back of the cam, not the distributor. In late 64 the 5 main engine was developed for the 1965 model and the electronic tach drive was born on MGs. PJ
