Todd,
Dave already asked me to help and he balked at my price. So, I may be wrong, but I doubt he's gonna pay to trailer the thing up to GR and let you wrench on it, unless you'll do it for free.
Dave's looking for a freebie. If I didn't have anything else to do, I'd jump in but I have paying clients so I can't afford to drop them to help him out right now. I'll offer my technical assistance etc, but that's about it.
