Adjustable brake push rod?

Gentleman: I caught this thread doing research for a 4 to 2-bolt aluminum MC switch. "Dr Diff" says their 2-bolt MC with provided 4-bolt adapter will accept the stock manual brake rod; at least for a 71 DART/Demon. The shallower depth of the 2-bolt MC is offset by the depth of the adapter. Does anyone know if a rebuilt/replacement 1979 or newer (non-front wheel drive) MC with the stock manual rod?

BTW, thanks "Abodyjoe" for your posts and info.
