Motor mounts

Why wouldn't they? The '73+ cars came with 318's, 340's, and 360's. With the exception of the slightly wider mount on the driver's side all the blocks are the same externally. The 318 mounts are reproduced, and you can use a small spacer (or washers) for the 340/360 blocks if you can't find a 340/360 mount for the drivers side.
