k guys, in the near future i'm going to be instaling a comp eng. 10 pt cage in my 84 z28, i just have a few questions.

1: my car is a t-top car will i still be able to get the t-tops on and off this the halo bar there?

2: will it fit in there without cutting the dash or dash pad?

3: when welding it to the floor in the front areas should i cut a hole i the floor and weld it to the sfc's? or just weld plates to the floorpan?

4: i'm a pretty tall guys (6'3") and if i'm wearing a helmet and sitting int the seat, the helmet is higher than the rollbar, thats not nhra legal is it? any suggestions on how to solve this?
