Autocross and Road Course Racing - 1976 Honda Civic- race resources?

I just bought a 1976 Honda Civic 1200 ITD car which I plan to convert to a vintage racecar. Any leads as to websites, suppliers, forums, etc that cater to racing 1st gen Civics?

check out Red Pepper Racing -- there are many people there with older Hondas (though mostly 3rd gen Civic/CRX). http://www.redpepperracing.com/

and there's always the Grassroots Motorsports forums, you never know what you will find there :) http://grassrootsmotorsports.com/board/
