Rzeppa said:Indeed, the 84 is a much better unit. Fully electronic, completely waterproof, wonder bearings. Note that it will have two different vacuum advances, a big one for your main advance, and a lesser one for HAC. Note also, that due to it's large diameter, you will need to use the side cover from the FJ60 2F, it has an indent in it to clear the distributor cap. Oh, one last thing - since it's fully electronic you will need to use the ignitor from the 60.
