Hey everyone i recently picked up a "Atlus" Sparco bucket seat last night and noticed the brackets and sliders i was originally was bidding on are off of ebay so now im kinda in a pickle. Would anyone know what exatly will i need to get this seat on? I ordered mounting hardware (nuts and bolts) directly from sparco but what else will i need to get this beast on? I originally had my stock seat until a family member was goofing off in my car and broke my seat N-e ways, If anyone could lend a hand that would be awesome! Thanks in advance
