The seller of this 1964.5 Ford Mustang Convertible claims it is a "D" code car that was optioned with the Rally Pack. While they have the Rally Pack parts, they currently aren't on the car. It was recently pulled from 30 years of barn storage and needs a complete restoration. If you interested in taking this project on, find it here on eBay.
Ford released the Mustang five months before the start of the actual 1965 model years, so cars built in this period of time are often called '64 and a halfs. The "D" code designation was only used for 1964.5 cars and that means this car came with the 225 horsepower 289 V8. The seller claims this is the number matching original engine, which is paired to its original four-speed gearbox.
The Rally Pack option simply added a Tachometer and clock to the Mustang's interior. Seeing as it was simply a bolt on option, they could easily be removed and installed on any Mustang. The seller claims this one's were removed to prevent them from getting stolen. If you look closely at the steering column, there appear to be marks for where it would have been mounted.
At first glance, this one looks very solid, but there is some serious rust issues that will need to be addressed. Early Mustang convertibles are highly sought after, but the seller's asking price seems high given the rust issues. They are willing to take offers though, so what would you be willing to spend on this Rally Pony?
