Looks very similar to the 100 series top links, but it has fine threads and the balls are category 3.  ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '63 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

| And, the fine threads would have eventually went away and were supersceded by coarse threads for longer life and durability. I wouldn't desire fine threads if it was mine. They didn't hold up well at all. I don't know why a 7000-8000 series link wouldn't be the same ?? except for the heavy-duty version, which was an option and waaaay heavier duty. I'm guessing 7-8000 series length is the same or very close to D-21's, 210-220's. |
