**** I forget. Let me talk to my buddie he'll remember

 

[fastestbrickonearth]

He forgets too. I think it is the same bolt used for the magnum 360 motor too. If you don't have the tool to figure out the thread maybe bring the bolt to a place like fastenal or another good hardware store they should have the gauge to tell you what it is.

I think there is 2 different bolts depending on the year. Mine is a 3/4" fine thread with a 1-1/4" head.

This brings me to my next question ,3/4 fine is the same as 3/4 npt tap ,,would this work on these threads ??

maybe at the end of the pipe tap, maybe

i would think there is too much taper on the pipe tap. if anything is open today, i would go get a thread chaser or tap to clean all the threads:rock:
