I am not clear you do have the overhang set correctly. Why do you say you HAD TO MOVE THE CARTRIDGE FORWARD to allow space for the connections??
In terms of frontward or backward movement in the headshell, there is only one correct position - the one that gives the correct overhand. If you set that correctly then the cartridge ends up where it ends up. If there isn't space for the connections then you're stuffed - get a shorter cartridge or an arm with a longer headshell.
@mwh777 Agree. Can't understand why some arm manufacturers don't design heashells that fit cartridges. I remember the Ittok/Asak. Asak was just about the shortest carteidge I have ever seen and the headshell matched it. I guess Linn didn't want people buying someone else's cart. Anyhow I sold my Linn about 35 years ago and bought a Zeta that fits most carts.
