Hi, Im new here and this is my first post, but I have a question I need some help with. I wont go into a lot of detail right now, but my main question is how would you replace the distributor on an 83 Blazer. Its the HEI- I know how to get it out and all that, but I'm just not sure what to do to put it in correctly. Do I just mark the position of the rotor and vacuum cannister and line the marks up the new distributor? Please help, this has to do with me getting my first blazer.
