I tried to install a graco myride 65 rear-facing in a 2008 toyota tundra, using latch behind the driver's seat. i attached the hooks of the grey rear-facing latch belt to the latch rings in the truck, and pulled the belt to tighten down the car seat. i was able to get the belt tight, but when i pushed on the car seat to check for movement, the belt loosened completely. i tried several times, and the latch belt would tighten, but it would not stay tight. i notified graco of the issue, and they were unable to send/sell me a replacement grey rear-facing latch strap, so they sent an email with information on how to obtain a rebate if/when i purchased another graco car seat. i can still install the car seat rear-facing using the seat belt, and forward facing using a latch or seat belt install.
