13. The most problematic bolts I ran into on this truck were the bell housing bolts. There is very little room between the bell housing and the firewall. The manual I have recommends pulling the body and core support bolts and jacking up the body to gain access. I decided against that and used a ratchet wrench to slowly turn the bolts out. I took a long while to inch the bolts out but they finally came out. The worst of them all was the bolt holding the trans dipstick tube, if I had hair I would have pulled it out.
