To be honest none of the 3 big tool trucks websites are all that great. Matco does not list old tools or any info on them, and some of there current stuff the links don't work right. Snapon's if you put in an old part number it sends you to the page for the current version ex F830 sends you to the F80 page and if you were not laying attention you would order the wrong repair kit or get the wrong info without realizing it. Mac's website is about the worst with small pictures for alot of things, almost no info on a lot of products.
