Thanks again for the info. There is a Chevy truck used parts place close to where I live and according to him he has the 4:11. I guess that I had better check again and make sure... price was mentioned and that may be the kicker. What seems to be the most elusive is the T85n trans. Missed one on Ebay last week from a 68 Chevy car. Thanks again I'll let you know what I find and if anyone knows of a T85 let me know.
