Don't sucker yourself in to buying someone else project

Finished up the brake lines, bled them and have pedal and with no leaks!

Motor runs, need to weld on a muffler and then I'm going to see about driving this green machine around the block.:D

I'm not really up on these late model 1972 cars and all the safety features they have. Whats up with this annoying door buzzer when the key is in the ignition switch? More importantly how do I disconnect it?
