When swapped to discs up front it was with the 68 and earlier units. Rotors for the early brakes (if you can find them) can run around $100 each. Screw that! Rotors for later units are under $15 each
I managed to find the 69 and up bits and while I was refurbing the kingpin bushings I went ahead and modded the spindles for more camber and to lower the front 1 7/8” . This way I can install the stock spring perch and regain suspension travel. I went ahead and made new upper bushings out of delrin while I was at it.
