Datsun Roadster Parts from Rallye Enterprises, Ltd.

Some of the pre-69 radiators had this as an original equipment drain petcock. Older engine blocks also had one of these in the drain hole behind the carbs. Later cars just went with a solid plug. Cheaper, yes, but it can be a problem to remove. This gives you an easy way to drain your block. All cars can use this in the block hole. Radiators before 69 or any radiator with std pipe threads can also use one of these.
