OK Timmayy, sorry for the delay. Here is what I was able to get from the dual pot reservoir and booster: The front of the reservoir is stamped with A1210 I know it's not much to go off of, but maybe it will be helpful.
Thank you, I was able to get one for a 67-69 Mopar. It's at my buddies shop right now getting done sometime next week.
Wifey's wagon is back on the road. Dual pot master cylinder works great. She already took it to the beach the other day.
That's great Timmayy! but there's no pictures of her longroof at the beach, bet she's happy it's back on the road!......Longroofs Rule!
Ok, added a water temp gauge, fixed the fuel gauge and the cigarette lighter so she can keep her phone charged (we don't smoke). I pilled out the aftermarket classic cassette radio. It was a mess of wires. We are planning to take it to a show this weekend. Hour plus drive. We'll see how it does. We have AAA.
A couple of small issues. New water temp gauge was acting up. Just a loose ground wire. I changed the plugs and wires. Tomorrow I'm going to get a new spare tire. So far so good.
The show went good. No issues. Hour and 30 min. drive each way. My wife actually beat me getting home. I don't push my slant 6 on the highway. The lower gearing in the 8 3/4 I installed in her wagon gives the little 273 a little more pick up. Next step is getting it aligned again. Since updating the suspension there is some vibration.
Before that, rotate the tires. See if that makes the vibration disappear, or move from front to rear. How old are the tires? If you're unsure or don't know, find the DOT tire date code, or codes if the tires are not a matched set, and google the translation. Anything over 6 to 8 years can have problems just coming to light.
