Lewmar genoa fairlead car

I purchased two genoa cars (Lewmar brand) and realzied after purchasing that they are too large for my t-track. I have 1" t-tracks on my boat and this car appears to be 1 1/4".

I've searched the Lewmar website and can't find any record of this particular model.

I did find part #'s 15200187 and 15200188 which are sleeve inserts for another Lewmar genoa car but I'm unsure at all if they will fit this car.

Anyone have any suggestions here as to how I can adapt this care to make it work?

Thanks in advance.
