Are pre 03 and post 03 swingers all the same? As I had a pre 03 powdercoated, extended +3 and new bearings etc went to fit it to my 03 blaster and wouldn't fit between the frame! I managed to rough it in but once the bolt was tightened it locked up solid. Would really like to put this on mine so I can use mine for my gfs build I'm thinking of doing shortly.Thanks Craig
