Mount/subframe question

A 70 Barracuda is an E- body, and the mounts are a lot different. You need 340 mounts for a 68-71 340 A-body. The drivers side 340 mount is different than a 318. You can use a 318 drivers side mount on a 340 or 360 by using some flat washers to fill the space. Shumaker sells repro mounts and insulators for 68-71 A body 340 cars.
