Kirk,
I have a ring, helmet, pins, tiller arm, bellows, trim senders, etc.. from my '99 standard bravo gimbal. Its a bit ugly in the usual places, but its solid with no play anywhere.
I have (3) used gimble rings which are in nice condition - I'll send you pic's if you need - I'll let them go for $90 each - you pick up the shiopping cost.
