Is there a measurement or a way to determine if my 63 Ply has the correct K member? I have a CSR transmission shield for my big block I want to use now. I know the "trick" years ago was to put a newer year K member in to move the motor back. I am not sure if the previous owner may have done this. I have had no clearance issues with the firewall but never used a shield before. The car is stored two hours away so trying to get some knowledge before I go check out the car. I know of one racer who had a problem with this issue. If the K member has been changed to move the motor back you can't get the CSR shield on as there is not enough firewall clearance. Would like to figure this out before I try and put the motor and tranny back in the car. Thanks for any info.
