Put new wheel cylinders in the rear brakes today. Couldn't find a source anywhere for US built, so had to put Chinese in. All went well except that I had a bear of a time getting the flare fitting to reseal, and it was probably those cheap Chinese wheel cylinders. Wih I'd have bought a rebuild kit instead. Finally got them stopped from dripping.
After that I installed the new MSD 6 ignition controller, and reset my timing for the hotter spark. Still need to open the plug gap from 35 to 50, and then it should be ready to go.
