Basically, use all the parts from the 73 set-up and just use the 67 vibration damper and make your own mark to match the new mark location on the 73 timing chain cover... It will save you a bunch of headaches... :BangHead:
If you still have the 73 engine and parts, you already have most of what you need and just get the piston stop tool to make a new TDC mark... :D
You will only need the timing chain cover and water pump gasket kit to change it over and then paint it to match... :steering:
