Perhaps you'd be willing to volunteer your time so you can implement your ideas, Cato, instead of expecting someone else to take the time and effort to explain everything to each individual member in a way that suits each of them best? Think the time that would take, and even if you drafted just one post to explain all of the changes, would you be willing to take the time to answer each member's questions and address their concerns until they're each satisfied? IIRC, Gregg let it be known publicly that the forum would be down and there would be a server changeover last Thanksgiving-ish, and there was still complaining. People complain when they don't get help quickly enough, when their questions aren't directly answered, and when they feel their concerns aren't being addresses to their satisfaction, but who's going to volunteer their own personal time to help Gregg, Harry, Dave Ambrose, etc. take care of it all?
The bench seat from the AMT '60 Chevy Pickup kit (the '90s kit) works well in the C-series interior tub, as does the AMT '57 Cameo bench seat. Might be a bit too late for you, but better late than never:
Andy, do you have one of the Goodyear Eagle ST rear tires from the Revell '34 Ford kits by chance? They might work with the turbine style wheels in the GL kit. I think I have both so let me do some test fitting today and I'll LYK what I find.
