Hello All. Thank you for your time. I was going to upgrade our 72 Buick skylark manual brakes to power brakes but unfortunately the donor car had a broken manifold fitting. The fitting is for a 350 manifold. It has an 1/8 male NPT in the manifold and then 90s to a 5/8 female metal tube fitting. I been to several hardware stores and a store specifically dealing with fittings and hydraulics with no success. Does any of you Buick people have the fitting I am talking of? This fitting seems to be Buick specific. Please let me know.
