So I did not have the two flange bolts. However the diesel engine flywheel housing had the holes with treads.
But my transmission housing did not have bolt holes.

Quick update on the clutch replacement.
The only place that seemed to have the Plate 2A2358 was Fresno Tractor. Even came in the original box what was super cool. https://www.fresnotractor.com/Home.html
Ask for Roman 1(559)269-8995
Also after I bought the whole disk, I found the friction material on eBay a chap in the UK had them available, so I bought 4 just to have. https://www.ebay.com/itm/186669366360
As to an update on the D6 318 block I have been looking for, I ended up contacting https://www.ihmusedparts.com/home They had a 1H5650 block with standard standard crank for a very good price including shipping.
Anyhow just some information.
