Plasticexperience

I am restoring my 69 L71. I just dis-assembled the front Spindle, knuckle and caliper bracket. The markings on the knuckle and the caliper bracket are correct.

I can't find anything on the spindle other than an "H" and "72B". The pics below are the only markings. It looks to me as it maybe a replacement part? I am having a hard time loading the pics but the markings are as stated.Bob Messina
