WTB manual brake pushrod for 1973 Dart Swinger

Old man,
Interesting strategy. Does this work with the '73 front disc/rear drums? It sounds like it would.
Also, the thickness of the custom made flange sounds like it would affect the outcome of the pushrob being the correct length. Are these new master cylinders from the 80's trucks cheaper? If they are more expensive or the same price, I'd almost rather just stick with the stock pieces, though not having the parts rust would be nice. My only concern is that the replacment master cylinders (stock) have a small reservoir and a larger reservoir, to account for the different amount of fluid required for discs and drums. Is this accounted for in the truck piece?
Thanks for your comment. I appreciate the help.
