Flex-a-lite makes one model for the Toyota trucks, #165 as I recall. That would be the one to get as it bolts right up in place of the fan shroud. Anything else and you'll have to fool with mounting it somehow. I ran one for a few years then reverted back to the stock fan clutch. Much more reliable and long lasting. I found the original one was getting a little too stiff so got a new one from Toyota and it is a lot looser and has lasted for probably 4 years so far. The one I got from Napa lasted me about a year before it blew up.
