...we do have some RH adapters. You would need to go through GolfWorks Canada to place your order. I am not sure if they have any in stock in Canada but they would get it from us here in the US. Yes the new TA 845 adapter will fit the TA-1 driver as well. You can call GolfWorks Canada at 1-800-387-5331 or email at support@golfworkscanada.com
Looks like you should be OK...
