Just in case anyone is needing this part and has noticed it isn't included in the brake hardware kit the part number is 1341-2. I got into a brake job on the rear of the 68 and noticed this spring was broken and needed to be replaced. This is the oval shaped "green" spring that fits over one end of the horizontal brake drum bar. Hope this helps someone out. This part isn't listed on the computer and the only way your Parts person is going to get it for you is to either know it from past experience or go look through the catalogs.
