Glenn -
Don't know what's available for this body, but you might want to look into a bolt-in 6 point. As long as you use adequate floor plates, it will meet our requirements and you won't have to chop up the car permanently.
As I must, let me suggest that you volunteer for the April meet while you're there. It's a ton of fun, you'll get to meet all the competitors, and you'll be helping us out. We are a completely volunteer organization, so no vols=no racing. Several of us both volunteer and race, and it works OK, unless you want to get in as many runs as possible.
