Skeeters65 45 #1 Posted August 19, 2016 Hey guys I bought a Suburban 400 last night that is in pieces. Just wondering if there is a list somewhere of bolt sizes and thread pitch? or at least what are the common sizes? Thanks Share this post Link to post Share on other sites
Racinbob 11,952 #2 Posted August 19, 2016 Some of the sizes are on the parts list but not all of them. I would say most all of them are 1/4"-20, 5/16"-18 and 3/8"-16 in various lengths. Nothing is metric. 1 Share this post Link to post Share on other sites
