what mounts are these ?
The left side is definately the 340/360 A body mount. The 318 A body mount is TOTALLY different. It has a tab missing that the 340 mount uses. Here's another pic of a 340 mount:
The right side is a bit harder. The 273-360 used the same passenger side mount on everything BUT the B/E body 318-360 passenger side mount is very similiar in appearance
to the A body. (Only the insulator mounting hole is different). Many people try to use a passenger side B/E body mount on an A body and it really doesn't work well at all!
This is the A body mount with the holes to the left. The B/E body when held this way has the holes on the right. Yours looks correct for the A body.
By the way, they are worth $40 to me if he doesn't want them.
