My car as converted to a dual master cylinder before I bought the var. The brakes are horrible, and I have had a quality shop working on it and we have decided that the factory knew best and want to move back to the Tredle Vac system and return to the factory spec's. The front brakes show little pressure till the end and then lock up, we have added a valve, but still no luck.

My question is I have no core, so many won't sell the unit without a core. Is there a conversion to other like a T-Bird/Mercury or other Ford part that may not carry the extreme price tag. I still don't have a core but know that other part numbers may be more available so not an important for a core.

Any advice is appreciated.
