THE PORTAL HUB - Pinzgauers, Haflingers, Volvo 303s and more!

I was going to install the flex pipes today on the pinz and the first stud i tried to loosen at the header snapped right off. Needless to say, i do not want to continue.

1) do you use penetrating oil or heat to loosen?
2) how difficult is it to replace the stud?

Is there some shaft left on the stud to get a pair of Vise grips onto?
If so I think where your heading would good, best penetrating oil you
can get, let it soak for several hours and repeat. If this is broken off
flush that would be a nightmare.
