How many classes would this eliminate me from?

The racepak fits perfect here, I'd move it up a little bit so I could see it decent but without a dash is this gonna hurt me? I don't know the rules in all the classes so I'm hoping guys that race different classes could enlighten me.

If it would ban me from racing certain classes i maybe competitive in, I may have to hack up the fiberglass dash to make it fit, which I really don't want to do.

I would contact the tracks I wanted to run your car at and ask the tech. people about this Same thing on different associations which have different rules and classes

Heads-up or shoot out/grudge races are the only one's I know of that require a stock type dash !!
