Went out today and purchased some new hardware for the plenum, throttle body, and oil filler hardware connections.
I’m glad to have Beechwold Hardware right down the street. They carry so many individual bits and pieces, with a decent metric selection. They also have all kinds of washers and nuts and seals in nylon, rubber, other plastics, etc.
Obviously, they don’t carry all grades of bolts and nuts, so I still have to get special ones for some auto related systems, but it is nice to have them as an options right near.
