No, I'm sorry my friend, but really I don't get it
I'm a wide Hipshot bass extender user
The modified piece only adds a few grams in weight to your startin' machinehead specs.
So, ultralite machineheads, much like the one you find out, are for ultralite sets, so you better use it if you already have a full, complete ultralite set or are goin' to buy and install it.
Otherwise, you need a BT1 bass extender if you own a USA MusicMan, 'cause your machineheads are equal to Hipshot HB1
Or rather a BT7 bass extender, if you own a Sterling by MM
There, machineheads are close to Hipshot HB7 ones
In these two cases I mentioned, you're gonna install a perfect replacement with no extra screwin' I positively discourage you to go any further with different experiments
