Umm there not the dodgy, you can fabricate yourself ones. These cost quite a bit for personally and im only chargin money for time in bringing the kits down. These arent the hinge and bolt jobs, they are the high quality gas pump kits. Anyways i just put it up as I am getting one personally and was seeing if anyone else was interested. As for gaurantee and crap like that, u can come down, ill give u hand putting it on, any problems, then we take care of it there.
