The only other way to do it on my Polara anyway, would be to separate the rear lamps and have one brake and the other a turn signal on each side. Bypass the brake light portion of the TS switch. Naw, I'll wait for Dan to get some switches in.
C body switch will work. See other in this thread.I feel bad about this whole thing. Finally found the time to change the switch. It went well. Thought the Shee-Mar was fine at first. Discovered the weird rear lights flash position. Shee-Mar was great on the phone but that didn't fix my switch. Tried Dan. He is out. Hard to find OEM switch. Almost ready to bypass the turn signal switch for brake lights and just use the trusty old hand signals. Or just drive on straight roads and never turn.
