I already have the stainless hinges for my stock doors, do I have to purchase another set to make these work with my existing? I have a 67 roadster with later model latches do I need to fab anything to make these work? Are these sold in pairs or just individual?

• Since it appears that you have to change out the door striker for these, does that mean the stock doors wont work with t fitment
• what kinda seats are those? general
• Do these come with a quick disconnect hinge (can just lift them out)? general
