zgeezer Posted July 4, 2004 Share Posted July 4, 2004 My 1971 240Z crossmember has three captive nuts welded to the inside of the trailing edge of the member. One of these small holes has a round head allen screw in place. Does anyone know what these captive nuts were used to secure? Nothing in the manuals I have identifies any use for them. But, I figure Datsun put them in there for a purpose. thanks g Quote Link to comment Share on other sites More sharing options...
280Zone Posted July 4, 2004 Share Posted July 4, 2004 The nuts are installed to have the fastener come up from the bottom of the car they are for the lower splash pan. A lot of cars have long since lost the pan. Quote Link to comment Share on other sites More sharing options...
