Brad is right on about the cracking at the upper part of the cross member. My '50 has the same problem and I suspect that it is the cause of the vibration that I've had at about 40mph. I've been chasing that for five years and haven't been able to nail it down and I probably still won't be able to test it till I do the frame off next year and can make the correct repairs.

I would really like to see some close up pictures of those HD motor mounts. I'm assuming you're going to replace them with the stock motor mount, I would really appreciate it if you could post a few more when you get them out in the open.
