Thanks Alan , I found them

Thanks Alan,  It suddenly occured to me very early this morning that I had a 68 swing axle tranny W/ 4 lug drums that came off of the original rusty Allison pan that I am replacing. Well Dud !!! I must be losing it. I have been tripping over it for a year. So I just need 2 adapters. I think I will just order new ones plus a few other little goodies from Moores.

i don't think you want to use adapters... especially only two.., on the front no less... just get a set of new drums/rotors and have them drilled for the pattern you want! no adapters needed!

Why ?   Never had any trouble before . Besides you can't re-drill a drum off a old model Link pin front end or rear for that matter on the account of the curve outward just below the wide-five flat pattern. Even if you could machine a flat surface on those drums, you would only have about
a 1/4 inch of "meat" left. Why would it make any difference to just run front adapters. I don't think the buggy would care whats on the back. Alan has been running adapters on his Allison for years.
      I don't think that anybody makes a 4 lug drum for a link pin spindle but if they do  It would be a no brainer and they would be on the way here, But I'm not going to drop a wad of money for a disc brake set up just so I wouldn't have to deal with adapters.
     If you know who makes old model 4 lug drums let me know who and I will jump on them as long as they don't cost more than my buggy.
    The only time I ever heard about a problem was when some Bozo didn't  take time to check on them or didn't install them properly from the "Get Go"

Hey , Something else. I just checked all of my catalogs and nobody sells or even offers a disc brake conversion for a link pin front axle. '66 up ball joint front axle only.
