What do you use to take the throtle body off with ? allen wrench?

 

You could give more details like what are you attempting to do.

 

Sorry trying to put the crawford plenum back on I have, cant get the throtle body off I put an allen wrench and it didnt work, maybe it wasnt the right size? or is there a certain tool you have to use to get it off

 

standard allen wrenches...I think they're metric ~ make sure it's a snug fit otherwise you might strip them. They shouldn't require much TQ to get them off...they bolt into the Al plenum - should be in "in-lbs" range.

you're talking about the 4 bolts that go here, right?
