johnny dart,,i may have one,,, but i think they are different on the drivers side for a 340 and a 273/318 and one know?? ill look see what i have

Drivers side is narrower by about .375".

You can make a small spacer. I've seen 1/2" bolts, 7/16" id iron pipe, a stack of washers, whatever takes up the space between the rear leg and the block lug.
