I have been working on tring to figure out some things on my 68 bird. I know the car is a ra1 and I know it's a early production car. The car originally came with a hood tach but appears to have been a tall style tach. I have been looking to find the rpm redline it would have come with you cannot find anything on such a topic. Also would be interested to see what week the first ra1 bird was built as mine is a early production car as well. Thanks in advance for any info
