dumb new guy question

I am being told I need to have a window net, by a friend of a friend that has been racing for who knows how long. (he says he requires one and runs about the same ET as me)

I have looked (as best as I can) at the NHRA rules to find if this is true for me.
however, I dont know what my car is considered, stock, super stock, super street or whatever...

stock = full stock interior = i do not.
super stock = correct block, heads and carb. = i do not.
super street = full-bodied cars and weigh no less than 2,800 pounds = i do not (car weighs less than 2800)

I will be calling Speed world to see if they could correctly inform me, as I'd like to go this Saturday (for the first time this year).

please, if you know 100% one way or the other, tell me!

my car has a full cage, lexan windows, ran a best of 10.89 @ 122

thanks for reading!
