I have several russell/edelbrock fittings. I know I have the one for the fuel rail and the vette fuel filter. Pm me your info and they will be on their way.
I think I may have other parts but need to get back in the garage and work on my own project and see what else I have.
Keep up the good work. I am sure you are making your father proud and that is a gift/felling that he will always remember.
