73 and up spool mount A body K frame

You will not find the washer on a 73 and up K-frame with the spool mounts. I believe after 72 when the change was made to the new style mounts, and the motor was detuned to the point of mediocrity, they deemed the extra welding unnecessary and just made one K-frame. I have an original 340 spool mount K frame from a 73 Dart Sport if you're interested. It would need to be shipped though!!! Geof
