For belts I suggest contacting Kevin Marti at Marti Auto Works. He does the "FoMoCo" stamped/dated belts for many Ford applications and used to make them for my business. He had/has a source for the correct width and does what I assume is a hot stamp process that embeds the text into the belt surface. I had him make about twenty different belt applications for 61-66 Thunderbirds and the belt cores were genuine Motorcraft belts so no worries about belt quality.

And I neglected to post the pricing information on the plug/harness setup....they are $47.95 each and shipping via USPS Priority is $7.50 for up to 5 plugs.

I will talk to the potential pulley manufacturer this week.
