Thank you guys, I see not definitive pattern for this - and unfortunately no real pattern either.

Recognize this was not my thread but Georges, i appreciate hearing the input and thoughts etc.

I was under the impression this was a pretty clear answer, especially for the 69Z cars, all had 12 bolts, boosters and masters with distribution valves and dump valves.

Obviously not.

Thanks again.....



I got it - there is conflicting info on what is right or wrong or no real definitive pattern for the application.
