How many bolt mounts should be on my Torque converter? I count only three, should there be more? Im thinking one or two might have broke off.. Dont know if this will help but my transmission is a 13 bolt pan, GM turbo 350, my truck is a 1976 k5 blazer.. By the way, I thought a rod was knocking in my motor!! Took a look at my TC and all the bolts where out except one that could be unscrewed by hand!!
