1968 292 Oil Filter Threaded Adapter

[Fieljekoel]

Hello,

I recently had my 292 inline six rebuilt, and the machine shop took the threaded adapter that you screw the oil filter onto out of the block, and never gave me back the original one. I was hoping to find out what part I need to order to replace the one I am missing. I took some measurements of the hole in the block, and the oil filter, and I think the block side thread is 1"-12, and the oil filter thread is 13/16"-16. I was wondering if anyone had any knowledge of this as it is the one thing in the way of me getting my engine started back up
