One major mod that I am looking at doing is putting suicide doors on my rear doors. I have looked around at kits and they seem to hover around 400 to 800, however this is just for the kit. Was wondering if anyone had any advise on going about it and making sure it is done right so that there is no danger of the doors eventually druping down and becoming misalligned. Also what is envolved in actually installing them, and an estimation on how much it would cost to have them installed professionaly if that is required. Any input you could give me would be greatly appreciated.
