We never offer this but we currently have 1 available. The LH Caliper is the impossible one to find. I've had a couple of people inquire about just the left. The problem we have had with these calipers is that despite the core charge some people decide they want to keep theirs for spares or just don't want to bother returning cores so as a result our stock has been diminished significantly which is why there is often a wait before we have calipers back in stock. Yes this caliper has a higher core charge and yes it's more expensive...that's because it's the hard one to find and we REALLY want our core back so we can keep offering this service. So the Core charge on this caliper is $300, this is refunded upon receipt of your good core.  Core must be returned within 60 days to get credit.
