I ordered new 168 dual bolt flex plate. From summit arp bolts and went with a boss hoss 2800 to 3200 converter. Hughes seamed maybe lil better quality but didnt have anything like that. Thy had a 22 to 25. And a 25 to 3000...the next was 3 to 3500. I thought maybe a lil high. I can always send back to summit if i change my mind
