I am not at the shop but need to know what the threads are on the adjustment screw on the top of the box that the jam nut holds in place. I know it is kinda obscure because when I messed with it a few weeks ago I didn't have anything that matched and then I quit messing with it. Sent from my iPhone using The H.A.M.B. mobile app
i just checked a genuine GM Vega box and it was 5/16 fine thread those off shore made reproductions may be different...metric?
Thanks 36! I'm guessing mine is metric because the 3/8" I had was still too small Sent from my iPhone using H.A.M.B.
I will also look when I get home. My 28 also has a vega box. I just assumed they were all the same. Sent from my iPhone using H.A.M.B.
