fwiw, according to Vixen's Porta Accy' page, #3942 is used by both original Porta and Porta II for 1/4" mounting.

It says it's supplied with the Porta II mount. The one that came with my Porta II is 10mm.
After just coming home with some 10MM bolts for another one of my Porta projects, none will thread into my Porta II.
So what pitch are the 10MM bolts would be the next question???
Silly me forgot to check the bolt boxes for that info and left the mount home so I was not able to cross fit/check.

It is 10 mm with a 1.50 pitch.
According to Home Depot handy dandy thread checker I had the Porta bolt with me to check.
In 10mm there are 3 different thread pitches.
What really grinds me is the 6- 10mm bolts I bought yesterday would not thread into my Porta, so after checking the Porta's against the thread checker I was really curious to see what the pitch was on the 6 bolts I bought yesterday.
The grinding part coming here,,, all 6 bolts according to Ace's handy dandy thread checker were all 1.50 pitch so I have no idea what gives here with me, must not have been holding my mouth right when checking the 6 new bolts.

I was hoping to hear from someone who has done such a conversion.

I have done this before and fine tuning my conversion
It's not as hard as most make it out to be.
So far the hardest part was finding the right bolt, but the one I wound up needing comes with the PortaII.
So what has to be drilled out and re-threaded?
