Hi Gus,
If you still need a navigator for Sandblast, I would like to ride shotgun for you, pending details. I have a lot of TSD rally experience and a couple SCCA So. Indiana regional champ trophies to show for it, but last time I touched performance rally was as a control volunteer at Sandblast a decade ago. If you're willing to work with an enthusiastic noob, I'd like to be it. I've got my own safety equipment, and I'm only a medium weight ballast at 165lbs. I'm also not a hyper-competitive or uber-serious type person, but I like to go fast and have fun. My typical time sink is a dual-engine Ford Escort crapcan racer:

Thanks!
