1973 duster window rollers.

Ok on my 1973 duster,build date 9-72.both windows have fallen.the rollers are busted up.mine have the ball ends that the rollers push on.the ones on ebay for 73 up are different.they have bolts in them.so I'm guessing I need early rollers kit?first pic is what a 73 up needs, second will be early.third will be a pic of one of mines-l225.jpg s-l225-1.jpg s-l225.jpg
