Well that turned out to be much more than I anticipated. Seems like there always.....something....
The following is my dremmeled screw- thanks for the tip! Also attached is old TB. Not nearly as dirty as I thought it would be. No catch can needed on the 4.7 it seems. 52k miles.
Sorry for all the seemingly easy questions but I just didn't want to make more work for myself if I did something wrong. Incident have any instructions. Although it is pretty strait forward.
Thanks again for all the help!
