1947 Flathead V8 Engine/Transmission install

[B.hotrod]

Does anyone know off hand what dimensions/thread measurements the bolts are that are used to connect the transmissions to a 59ab Flathead. The car has a 3 on the tree.

I’m about to put the rebuilt Flathead back in the car but bolts weren’t labeled when taken apart. Thank you in advance!

Thank you Bob C! I had the engine painted after the rebuild by a local body show and was worried about running the wrong size tap through the threads since the paint is thicker than spray can paint.

Thank you for sharing that Corvette8n, I will be sure to keep that noted along with everything else that I’ve learned about Flatheads since we purchased our ‘47!
