    Valve Lash Adjusters Worked.
    We were told that the valve lash adjusters were no longer available from any other source other than this company. We were disappointed until I googled Toyota Land Cruiser vintage parts. CARiD came up with a replacement part that said "Ford" on the card of 4? Well they work just fine even though the fit was a little loose they tightened and worked as well as the original adjusters. Thank you CARiD for the research to find a part that works when the OE parts are no longer available. These Toyotas can be restored even though the parts say they are for ford vehicles. We are very glad to have used CARiD and will use the company in the future. Lee Walker service manager at Bairds Automotive.
