I have a 71 FJ40. The speedometer wasn't working when I bought it but the seller said it just needed a new cable, which he provided. Well, it turns out the cable was fine, but the fitting at the instrument cluster was not. The plastic fitting that you thread the speedometer cable into is cracked so the cable will not stay connected. Looking online, I can't find a replacement instrument cluster or speedometer for a 1971. Any suggestions?
