Extracted and replaced the breather studs without issue...hour total. My friend got in there w the drill w out havin to take out fan housing.

 

you should have taken a video!

 

i wish i did. my friend who did it is a home improvement guy...not even a car mechanic...although he does alot of work on his cj-7, he never drilled a stud out of an engine block.
Jose...he is great at modifications..like the one you just did in your car w/ the classic center tray. i showed him that and he loved it. were going to do something to mine..just not sure what yet.

 

as long as you don't put an aquarium in there!
