Everything is worth something relative to what is being swapped out or eliminated.
A single cylinder master cylinder is not too heavy, but heavy enough for my taste. Back when, supposedly a company called Girling was making aluminum single cylinder MC's for the 2% cars. It has not been verified though.
I have now reached 11 ounces removed by a few bolts and nuts up front.

This 1600 ounces = 100 lbs is going to be the hardest demand on my lose bolts left in my head. LOL
1,599 ounces left.
