eBay auction currently running, expires 27 September. These are the OEM bars for the Mk1, and quite rare I believe.
Certainly getting a lot of interest (have to declare a personal interest - I am the seller).

or search for "Toyota MR2 MK1 W10 AW11 - OEM Ski bars / Roof rack"

The link got taken out as it was my first post, so here it is again:

Thanks for looking. Lots of interest globally, and sold to a UK buyer for over £800 in the end
