Motor Mount Brackets....

driver side is different...

you can use the 273/318 bracket on the 340/360 with a spacer or stack of washers.
Yep found that out going to a 340 FROM 318. drivers side different. The piss off thing had to wait few weeks to get the correct set from Mancini. Wasnt surprized but young buck behind the counter at Chrysler never heard of a 340, "You mean a 360" Lol D
