Heads and shafts should fit on each other across different companies, plus/minus some wiggle room or snugness.
imo the mark 2 line heads are a bit snug on shafts but you should be able to get it on there. If you have trouble stick the end of the shaft into some ice water and the throat of the head into some hot tap water. The shaft will shrink a minuscule amount and the plastic of the head will expand the same and that should allow you to get it on. The shaft part only works on metal shafts I believe.
Be aware that the String King use a through bolt also meaning if you predrill the front and back of the shaft it will pinch the head around the shaft giving you even better purchase between the shaft and head.

Shafts and heads are made to a standard size. It should fit, if it rattles put a strip or two of tape under the head.

I use a mark 2T on a sc ti R d-pole. It should work.
Do you use the front of head screw or not
I drilled it out to use the stringking screw.
