Blazer Tech Adjustment Kit

Does anyone have any info on the original method to install the blazertech lights. Originally when I purchased them, I also ordered a kit containing bolt, spring, plastic thumb nut for easy aim adjustment. Since purchasing I need to replace the bolt and thumb nut. I just don’t remember where I bought them but it was referenced in the original directions on how to modify the OEM light bracket for use with the Blazertechs.

Thanks
