Marlin, the stock rear sway bar is .75" while the stock front sway bar is .875". The picture I posted is a .875" bar and I have been thinking that it is the front. I had it laying it next to a rear bar and it seemed to have a different shape. I am guessing the bar you have is a front since it is .875", otherwise it would be an upgraded rear.
...Correction Made, Bar is 0.790" by Calipers. It IS the Stock Rear Bar, because I took It off the Rear of a '74L! Comes with All Original Bushings and Brackets. And Yes! The Bar You have Pictured IS the FRONT Bar, due to the Farther Spacing of the 'Stops'.
