I'm thinking they are different, samuraidan. 1st gens were longer and 2nd gens shorter... because of a slight difference in frame width (hence the Sidekick Sport with fewer aftermarket parts) but then if it is really a "stinking good deal" then buy them and try them and if they don't work pass on your stinking good deal to someone else with a 1st gen truck. All it will take is your time, some elbow grease and maybe a replacement bolt or two. Or.... maybe they are close enough that you could mod them with some custom cutting and welding?
