I too have a Mac Dingy with Main, Jib, and Spinnaker. I am the original owner and have sailed it in 1978 from Homestead FL to Key West in the Atlantic. Mine is all original and for the most part in good shape. The rudder blade broke off shortly after my keys trip but I was able to make a replacement. If anyone needs photo's of any parts of a Mac Dingy please let me know and I will be glad to send them. We are in the process of downsizing and may consider selling it for a reasonable offer.
