Roll bar advice/help

I just brought my Miata up to Boston and want to do some autocross. I noticed that a roll bar is a requirement for Palmer. Thought I would check here to see if 1. Roll bars are required for your autox events and 2. Is there anyone with experience that would like to volunteer to assist in installing a roll bar with me ? I am thinking the hard dog hard top m2 with dual diaginals (I have a 1997 na but it has a glass window in the soft top and this one seems to meet just about any requirement)

Bars are not required at Renegade, SCCA or BMW CCA autocross for cars with any tires. They are also not required at the two Porsche clubs for cars with street legal tires only.

Awesome thank you very much for letting me know before I started chopping her up, I see that you guys have an event next weekend. I will come out to spectate/make sure she can make tech for the next one!

Palmer would be track/HPDE, not autocross.
