Hey Eric,

Prefix got back to me they have the main stud in hand which looks to be like a 7/16-14 coarse thread on both ends. I had asked for the specs but they didn't respond with detailed info?

They are $10 bucks each and I had them ship one to you via the cheapest way possible. I'll send you an invoice but don't worry about it right now. I would rather have you pay me in person at the Spring Fling Speed Festival at Big Willow in April 2019 haha!

If anyone else needs one please email us your zipcode.
Thanks!
