GM Hydro Boost

[002]

I am equipping my m-37 repower/disc brake conversion with the GM Hydro Boost brake system like many others have done. Rather than junk yard parts I purchased remanufactured hydro boost and master cylinder from NAPA. However the rod and spring that is required must come from a GM Dealer. I have attached a link from a very recognizable source that I sourced parts from. Reliably reported as part #’s 377397, 471736, 360859 and P155581525. GM dealer says they are obsolete and can’t find any on their parts locator. So I find myself looking for Chevy parts on a Dodge message board. Other than the obvious junk yard search for a potentially 30 year old parts truck or Ebay (which turned up nothing) what say you. For these parts used is fine with me and I am certainly willing to compensate and pay shipping.
