[Roadsters] Roadster Air Conditioning

[Krismon Ongbongan]

First of many hot weeks in Las Vegas this week, and you guys all got me
thinking AC.. I just spent an hour online looking at different kits and
such. Then I realized I don't even have a working top for my car yet.
Priorities! That said, looks like nostalgic air makes kits for MGB and TR6,
I wonder if there is enough Datsun demand for them to make a kit for our
cars (and what the premium would be)?

Kris.
