Is this legal?
 

I was told I could use an anti-rollbar on the rearend in stock but it had to be a bolt-in unit.
Is it legal to weld in box tubing for mounting the anti-rollbar?

looks bogus to me. If I was from that area I would protest.

And the "rule book" says what about anit roll bars???

Re: Is this legal?
 

ahhh...I think it says nothing....traction devices are "supposed " to be bolt on, anti-roll bar is not a traction bar, I've looked under many stockers,lots have them and all were welded in.

Re: Is this legal?
 

^^^ Yep! Mine is welded in.

You can tack weld the anti roll bar in place and bolt it, but i was told you could not completely weld the unit in. Thats the way mine is put it, works great and never had a issue.

OK, if it's not a traction device then what exactly is it? Why do you have it in the car?
To answer the question, no it's not legal but all of the late model F bodies that I've looked at have them welded in and the particular kit in that article is meant to be welded in.
NHRA should spend some time looking under cars instead of just looking under hoods.

well the rule book says you can "beef up" the frame, and the anti roll bar is technically bolted to what ever extra "bracing" they added

Re: Is this legal?
 

I can't find that one. Could you please point out where that is in the book?

The frame can be "beefed up" in stock?

I looked for that in the rulebook before I asked the question. I did not see any such statement in the stock section. The only allowable addition I can find is the connectors between front and rear subframes.
