I need some advice on Roll cage fab

[AJohn6]

I have a question for the chassis experts on here. I have a '71 C10 which is currently under the knife. My plan is to build a pro-touring style truck that is capable of mid 10's in the 1/4 mile. I do not have a good knowledge base of chassis/roll cage rules and would like your help. I purchased the 1 5/8 EWS 10 point cage from S&W and need to get good advice before I start cutting things up. *** Also the firewall is modified.

1. Do the outriggers have to be welded to the frame or can they have a plate welded to the end and then be bolted to the frame with grade 8 hardware?

2. Or.. can the outriggers be welded to the frame and the main hope/windshield runner be bolted to the outrigger with grade 8 hardware.

3. If running, let's say, 10.5 in the 1/4 are the rear braces (from main hoop to rear frame) needed?

4. Is there a maximum distance that the rear braces can drop down from the main hoop before it has to go out of the cab of the truck?

The reason I ask #1 & 2 is I would still like to be able to remove the cab after putting the cage in. And the reason for #3 is I want to avoid having anything come out of the back of the cab.

Thanks in advance,
