Herb,

I'm going to assume you're referring to a stocker, right? I'm reading from the IHRA rulebook (because that's what's in front of me, not sure where the NHRA book is, lol).

It states: "Round tubing may be used to tie front and rear subframes together and join subframe in straight line extending through car floor, with floor completely welded to member." Keyword being MAY, meaning you can use round or box material. Says to me, you can run the material through the floor, just needs to be completely welded, so the floor of the vehicle is resealed.

This is how I intend to do my crate motor Firebird, when we tie the frames on it.
