Engine mount confusion

I have been working on this for way too long. I can't even figure out the engine mounts.

The one for the driver side is a tad too wide. And the passenger double holes are on the opposite side of the block double holes.

What am I doing wrong.

Yep, 69 Coronet. Originally a 318 car. I suspect that k member is also original.

The thing that is throwing me off is that these mounts came off this engine and k member about a month ago. I'm guessing they they "made it work" on the conversion. I didn't know what to look for as I took it apart.

I was planning on reinstalling the engine and k member this weekend but I guess I should wait and get the correct mounts now that I know my mounts are wrong.

I will check the marketplace for some 340/360 mounts. If I can't find any I will give your business a call. I'm also in Seattle. Thanks for the info.

If you are in a hurry you can "make" them work. Lelo Dart is right, you can shim the drivers side reward lug if you want. Just snug up the forward two bolts and fill the gap in the rear until it's close and then tighten it down. The passenger side is only missing a hole. So if you have access to a drill press and a 1/2" drill bit you can drill out the 4th hole. Easiest way to be accurate is to clamp the bracket on it's side with the 2 holes facing up. Use the existing hole as a guide to locate the missing one on the opposite side. Of course you could measure, if you want…duh. The side holes are on 2" centers. Now you have the required 3 holes to mount the passenger side and you are working this weekend.
