Retainer ring for 3135 movement?

[cacti]

I'm swapping out a VR3135 for a VS3135 in my 16610 and the VS is slightly larger and needs a retainer ring to hold the movement in place.

I can't for the life of me find a 3135 retainer ring. Anyone know where to find this?

Doesnt exist. Just use longer tabs. 3135 movements just drop in, they dont use any sort of movement ring.

Must be the case, the VR fits but the VS is a little loose.
