My mag post was so far down I wanted to touch base with you on your replies. RG I have a mach shop that will do the job but they had some ?s that I could not answer, they had never seen this setup and asked me to see if anyone had done one as they too were concerned about damage to the housing. So have you had the bushings removed on yours or are you like me ya just know it would be done best by people who do this sort of work every day. Den on your reply here is my thinking, The F/M dist lugs to the cam are a different size and it goes on just one way if you do it wrong you get to buy a new dist. I have removed my mags to have them rebuilt over the years a few times and it seems to fit fine in either slot or I have been lucky if they are diff size. Maybe if the lugs are different then the F/M dist it would be due to a heavier load of the mag drive gears and not just needed to turn a rotor. I will put a mic on them but they look the same size just with a eyeball. I can see the F/M dist lugs are one sm and the other is bigger with a eyeball. Thanks for the help.
