Tronman, thank you for the insight and recommendation. I understand that the donor S10 system is not really compatable with my system so your recommendations regarding a path forward make a lot of sense. I do not know but suspect that the donor S10 did have ABS as it was a later 90's vintage and I beleive that S10's of that era all had ABS.
I am not a fan of salvage yard brake parts but using a 90's vintage 1 ton truck as a model I should be able to determine what master I need to combine with an adjustable proportioning valve to dial in my brake system.
