To the first-Joey is correct,if the fit is in question by all means help the guy out.If the price is in question PM.If you can agree to a price Great,if not,noone has been hurt.Dont believe that i remember the pistons and rods ad but;wouldnt it be more appropriate to pm this guy and talk to him?Maybe he just doesnt know what they are worth.But then again maybe he does.And who knows maybe you will make a friend.
