You going to need to measure the sockets you have then check the specs on the technical drawing. They look like they are in millimeters. You will either need good eyes, or a metric caliper. Assuming these are out of the truck for measuring.
With out buying them, there really is no way to tell. I was going to swap the idiot lights over when i did the led conversion, but I didn't find these till after the fact.
Other option would be to mod the sockets you have with 12v leds. This is not fun. I burned my fingers a few times modding my theft light to blue.
