I would just contact LOC and tell them your situation. I can't imagine they'd charge you.
Might even be worth asking if they'd send new fins. The new design is much more robust than the old tab lock fin design. (If your kit isn't the latest revision)

Enough 4F isnt an issue for me, Steve.
My tools are not all out of storage or are still boxed up since my move. Making a CR is my problem.
Costs more to ship one than the ring does I think.

I know Mini Mags are short but I would want the forward most ring far enough forward that you don’t have a lot of body tube to pressurize for ejection. 38s don’t usually come with a lot of black powder. I would make a 3rd ring
and position it as far forward as is practical.

I would think at the top of the TTW fin tab would give the best support... But how far past that point does the MMT extend?
If that ring is not at least slightly past the midpoint of the MMT, I'd be looking at other options... Perhaps some shims at the leading end of the MMT tube vs a full ring?

This rocket uses a Loc 5.5 in airframe with a 38 mm MMT and will fly H-J motors.
I have only 2 centering rings. Adding a 3 ring is
not an option.
1: the forward ring in the most forward position at leading fin tip
2: on top of the TTW fin tab?
The other will of course, will be located behind the fin tab.
