Hello, T-Mar. I am responding to your request for date codes on the Fuji Special Road Racer which I had mentioned previously. I have now viewed the Vintage-Trek site. Inside the left Sugino Maxy crank arm I find "forged 171 48-3." This indicates manufacture on March, 1973. On the back side of the front derailleur I see the letters "PD." These suggest that it was made on April, 1973. I've not yet been able to find other codes. I may have to do some disassembly, when I get time. However, considering that this was the period when Japanese bikes were selling rapidly, spending little time in warehouses or on shop floors, the bike itself may be a 1973. Again, best wishes for your efforts. -Yamamori, jitenshasuki
