Kevin; While I don't have one, the number you have in your post is probably the short stamping number. My parts book indicates "Rod Assembly-Engine Connecting" for a 351C (Boss) to be a D1ZZ-6200-A.
Now for my story: Two weeks ago, while restoring and rebuilding the 351CJ for my Pantera, I discovered a bent push rod. Went to the local Ford dealer, with the number I needed, he typed it into his parts locator system only to discover that a dealer 20 miles away showed he had 2 in stock. Called the dealer's parts department, confirmed the 2 in stock and two days later UPS delivered them. What was interesting is that the parts locator information he provided me had about 10 dealers listed as having various inventories of the the part.
Not saying you may find one this way, but it may be a "shot in the dark".
