Compatible drives for IBM Thinkpad T43?

Hello all. Does anyone know of any slimline dvd burners for a thinkpad T43? I just received a NEC 6650, only to discover that the drive is 12mm tall and my bay on the laptop is (anti)standard at 9.5mm. Needless to say it’s not going to fit, so I’m stuch with the stock dvd-ram (dvd ± rw) drive. It burns at 2.4x, painfully slow.
