I installed a dual master cylinder in my F. You can try one of 3 part #s?20/1323; 10/1323, 20/1323M. We got ours from a local Carquest parts store but I assume NAPA or any of the others can get them. Unfortunately, that?s the easy part. These part numbers are for rebuilt units and we ordered them 1 at a time and returned them until we get one with the cap held on by a bolt because the bayonet type doesn?t have enough clearance under the booster. In the case of my car, the 3rd one we got fit the bill. You will also need to modify the plate behind the master cylinder for fit. I?m not sure whether your upgrade is for an F or G but we used a GM style front disk kit which required 15? wheels. I tried to top these with a full set of Wheel Vintique Chrysler wires but we couldn?t get them to clear the calipers. In the end I used steel wheels topped with a restored set of G hubcaps I bought from a club member. _____ From: Chrysler300@xxxxxxxxxxxxxxx [mailto:Chrysler300@xxxxxxxxxxxxxxx] On Behalf Of Carl Westman Sent: Friday, May 02, 2008 7:03 AM To: 'jean-yves chouinard'; Chrysler300@xxxxxxxxxxxxxxx Subject: {Disarmed} SV: [Chrysler300] dual master cylinder I awaiting a dual master cylinder that should fit with long rams from AAJ brakes???.but it looks like the delivery have stalled.. http://www.aajbrake <http://www.aajbrakes.com> s.com <http://www.aajbrake <http://www.aajbrakes.com/> s.com/> rgrds..Carl Från: Chrysler300@ <mailto:Chrysler300%40yahoogroups.com> yahoogroups.com [mailto:Chrysler300@ <mailto:Chrysler300%40yahoogroups.com> yahoogroups.com] För jean-yves chouinard Skickat: den 1 maj 2008 23:37 Till: Chrysler300@ <mailto:Chrysler300%40yahoogroups.com> yahoogroups.com Ämne: [Chrysler300] dual master cylinder Hi all. Anybody know of a company or person that would be knowledgeable and could recommend a dual line brake master cylinder. It would have to fit under the brake booster on 60-61 cars. I want to upgrade to disc brakes... Thanks!
