Thanx.. I have read all that and I am going to convert to vacuum.. I am the original owner of this car and the brakes have been marginal at best.. I am on my 3rd accumulator ball... rebuilt M/C...etc...... I can convert to vaccum for less than the cost of a new motor using new stuff..... I am tired of the problems so I will solve it now and do it right.. If vacuum is good enough for the Turbo T/A's it's good enough for me.... TBF
