Looks like the kits can be ordered. That's the good news.
I spoke with Ryan @ Ryca on the phone today and the kits are almost ready - some parts are held up in shipping due to the Long Beach strike or some such thing.
Will be sending them my tank and hub tomorrow! The parts are boxed up and ready to go - duder at Ryca said that about 1 in 5 tanks show up with shipping damage, so pack carefully, and consider shipping the parts separately... I took him up on both recommendations.
