Hello Oldtime, welcome to the forum. Nice to find another victim of oldenginitis. Pictures are easy to post, there is a button called "Attachments and other options" just below where you type your text. If you click on this button it should give you options to post pictures, provided you can remember where you stored them.
With regards to spare parts you should look up Rob at Old Timer Engines in Petrie, Queensland. Failing that contact Gary at Diesel Electric Services in the USA.
