Cozy Sidecar I-bolt Mount Metric

I believe this is a Cozy Sidecar I-bolt. It is 96mm in overall length. The shaft upper part is 9/16"  (14mm) in diameter, then it steps down to 3/8" (just over 9mm).  Threads are 7/8" (22mm) long. Shaft is 59mm long (2-1/4"). Head is a little over 10mm thick. Bolt hole is 12mm. I just have this one in stock.
