That is rather rare! Nice steering wheel. It is rather rare because they only made the e-shift on the steering wheel for '98-'00 GS400's (just leather) and on the '01-'05 GS300's (mainly leather). Yours is wood grain to boot, I guess because it is sport design. In order for me to do this mod for my particular car I would need to find someone like you (lol) with this exact steering wheel and then look for a 2003 RX300 airbag (because it will fit in this wood steering wheel yet have connectors to match up with the GS400). Overall it will probably be around $1000 to shell out. Or have someone do it for $600+??? I might just try to get it re-leathered...$200???
