10 cents hey. did you have to drain the brake fluid and clean the resovoir so the jb weld would stick? I looked on line as well and they recommended also trying a freeze plug but couldn't find one that size roughly about 3/4 of inch in diameter. I found one place on the net where they sell the glass for $13. but 10 cents sounds even better. I also like adding value to things so this is for me.
