I am wondering if anyone knows the size of the rivets for the Prius fuel door. I think they are 3/16 but can not find this information anywhere on the internet.
Maybe just ask a dealer for a pair of 90269-06017 ? Then you won't even need to know what size they are, but you can measure them if you want to know. If I had to guess, I'd guess they're metric.
The substitute for 90269-06017 offered by the Auto-Vehicle Parts Co., Auveco no. 21315, is shown on their catalog page 314 as having a 1/4-inch diameter, and other suppliers give similar measurements.
