I was just wondering why the vgt was ever even trying to be removed, i see why now.
I always have good luck with snap on 10mm 3/8 drive 6pt impact wobble sockets for the lower bolts and a 3-4 inch extension, you have to be carefull that the socket is all the way on, but thats how i always do it, i also have a good long handled flex head snap on ratchet that works well for leverage.
