1978 911 SC connecting rods

Engine

Vehicle Information: Model: 911 SC; Year: 1978; Body Type: Coupe; Total Mileage: N/A;

I'm rebuilding the original engine in my 1978 Euro SC. It is a genuine Euro Car and I have all documentation on the importation. I have one connecting rod that the machine shop says is no good. The bearing was non existent so the crank journal and that rod were hurt pretty bad. The crank has been cut and polished to one size over. I need to replace the one connecting rod but I'm running into a strange part number. My rods have part number 911 103 105 0R, then there is a letter S in the middle of what looks like a W. SC's seem to all have a part number that starts with 930. This car was an early 78 and I've run into things like the fuel filter being a 77 part. So I guess some left over 77 parts were used on it. Even looking at 77 part numbers - nothing seems to match this number. I'm in a quandry as to what to do next. A complete set of new or newer SC connecting rods would be very expensive. I have another long block in the car and planned to sell it when I get the orginal back together.
