If you download their 2018 catalog is has part numbass and if ya google it summit sells them for 563 Part number 6412SJT. Maybe yall know about it already but its nice to see a price am waiting on the pictures and stuff before i jump on them. And yes I know 15/8 is perfect but I wanna be different.
