where to get these tools?
 

i have a plug on my oil pressure fitting on y 8.1L silverado. the plug has a square fitting in it and its not a 1/4 or 3/8 ratchet type. ive tried allen (hex)wrenches but none of them fit tight enough that i can get it loose. i dont want to mess the fitting up HELP!!!!!!

did you try metric?

yes i did, ugh this sucks i jsut want to put the fitting in it!!

got a pic of the fitting?

like i said its a square fitting liek the drive on a ratchet, except ratchets wont fit , are there special tools for this?

I'm sure there is a special tool but if you've got a grinder (bench prefered) and an old large allen key, get to grinding :) . I've made "special" tools this way and welders also help to add material if you need it. It doesn't have to be pretty, just functional.

yea...i have a set of those at work, got them from snap on....ill see if i can get u a part number

or you could look at an auto parts store they
may have something
