Howdy Mig, welcome. I have only heard of one store proper that sold em besides spooky in AZ.. Any way, would contact Manic Mechanic.
He is a good guy and down your way. Also a member and sponsor here. He doesn't sell kits but does sell all sorts of parts and can advise you well. Also read, read, read. Every thing you can ask is here some where and will answer questions before ya think of em.
These things are great fun and hope you enjoy!
