Anyone know which I should be using? the only difference I see is bore diameter, I bought the smaller one, should I swap it out for the larger one? The car is a street car....

James, what do you mean by increased pedal feel? (Havn't had my coffee yet so I'm not awake yet)...Sent you another email too..

the smaller bore has an increase in pressure over the larger bore. but the BIG thing is you can get these at your local parts store for around $40.

Rick from Mopar Action sells the master cylinder and adapter on ebay; they are supposed to be better than the MP units...
