aluminum 4-speed tail housing

Building a 68 fastback drag car that was last raced back in 76. Using parts that were made before this date to keep it period correct. Not a #s matching original hemi car or even a clone, just a vintage race car built with the parts that were available at the time to fit within the rules for the a/modified production class. Thanks for asking. I didnt want anyone to think their is a problem with passions parts. In fact I have a aluminum 18 spline in another barracuda that was built in his case. I believe it to be of better quality than any of the early factory castings that were made.
