Fender cross fitment....
 

OK I know this much:

rear fenders for 67 to 73 standards & 71 - 72 1302's are the same

and rear fenders for 74 to 77 standards & 73 to 79 1303's are the same

front fenders for 67 to 77 standards are the same

and front fenders for 1302's & 1303's are the same too (only the bumper holes are different

That said, will any rear fenders fit ANY year beetle? Are the only differences in the rear fenders taillight holes/mounting?

I have a 1302 and was wondering if the 1303 fenders will fit... Are the taillight plugs themselves the same? Meaning, will I have to jerry rig wires to connect my 1302 wires to the 1303 taillights?
