Re: '60-'62 POwer Brake Booster Adapter Bracket With A Clutch

There is one 5/16"-18x 1-1/4" bolt and one 5/16"-18 x 1-1/2" bolt that are both used to attach the clutch master to the firewall with the 3/8" spacer between the clutch master and the booster bracket. The 1-1/4" long bolt is used in the bottom hole and threads into the pivot block. The 1-1/2" bolt is used in the top hole with a nut and flat washer on the inside.

Yes the '79 master will work fine on the '98 booster. I do not know how to test a proportioning valve without connecting it and running brake fluid thru it. When bleeding the system, either gravity bleed it a while first, or bet the centering tool from POL to keep the internal valve from sliding over and cutting off flow to one circuit or the other.

Yes the clearances are a little tight. If I moved the clutch master closer to the brake booster/master, you would be limited to a smaller booster. The 3/8" clutch master spacer helps some with the clearance with the electrical plug.
