I am pretty new to Mopars so need some help from you guys. My 63 Polara 500 had been converted to front disc brakes but there was no record of what kit was used. I need to replace the master cylinder cap but have no idea what master cylinder they used. I can't read the numbers if any on the bottom of it. I have attached a couple pics to see if anyone here recognizes which master cylinder it might be so I can get a cap, or a new master cylinder I can buy that would work for this setup. Any help greatly appreciated.
