John,

From what I'm seeing in the parts books, the 1600 had its own rod, different from all the other models. I might be able to figure out what it is supposed to be based on the adjustment figures in the shop manual along with some measuring.


Maybe your neighbor has a 2 or 4-80? They used the 283 direct injection engine, but had an integral frame. They definitely looked different from the other Olivers. Get me a serial number and I can tell you what it is. 

Thanks for the help. 

And how's Issac doing? Isn't he going to be 2 soon?
