I Let it soak in some P B blaster for an hour and it tapped through. the piece you are not sure about is the piece #11 goes through but is not numbered on part diagram you posted. thanks kirrbby... sometimes I forget these are 40+ year old parts and need some force
First step is to have the sheriff stop over and run the vin, then off to get blasted and painted. Forgot that my pogo's are the quick release ones... might want to hang on to those.
not sure if the later years have a open and close valve on the fuel cap like the older models do but its worth a look. might not be open and starving for fuel. just a thought. oops racerx bet me to it
