69 351 w/ fmx question.

Hey all,
I have a 351w with the fmx transmission i am putting into my '51 ford deluxe.
We pulled the engine out of a 69 cougar, and I have lost the torque converter/flywheel nuts. I need to know what size and what thread to get.

Any help would be appreciated. thanks all

 

Also while I am at it. I need to trans cooler lines, I am using the stock rad so all I need is just a place to get the lines. we had to cut them to get the trans out. as they were rusted solid.

 

Get em @ a ****** shop. You won't find the right ones @ a hardware store.

 

99% sure they are 3/8-24 Serrated Flange nuts (not 100% thought)

 

Ford Parts Counter....eliminate the errors of guessing. You'll have fun with the younger counter guys that think the C4 is a Corvette style nomenclature.
