the original barrel bolts where made by stanley.
stanley still makes barrel bolts with the scalloped sides.
i ordered a 2 1/2" stanley bolt. the body has the same width. the bolt is 5/16 and the original is 3/8"
this will work if you install a longer pin or install it closer to the edge of the latch plate.
