Hi guys Im new to the site and I have read so interesting problems.I have one of my own.I am restoring an 82 shorty and im having a hell of a time refitting my front fenders.Dont get me wrong I have removed and replaced at least 50 front clips but I have never run in to a problem like this.Let me explain.I am useing a rad support from a 83,its the same isnt it.I am useing the same mounts except for blasting them clean and painting them.when I put the fenders on the rad support is two inches to low.HOW CAN THIS BE.Its driving me nuts PLEASE if you have any ideas let me know it would begratefully appreciated.Thanks RICK.
