Re: The seldom seen 1966 Sport Trim option - a REAL short wideside has been found!
Good question, now that you mention it all the TH400's I have seen in original '66 trucks have been C20's/C1500's. I do think TH400's were available in GMC C1000's with V6's as lizzemiester stated. I'll ask over on the 67-72 Chevy Truck Forum, someone there might know.
