Im swapping out my 10 bolt for a 12 bolt and im trying to get the rear brake line from the top of the diff. removed from the hard line that comes down the frame rail. It is stuck like nobodys business and i tried a line wrench and wd40 and penetrating oil with no luck. Any ideas. Thanks guys

You may have to resort to heat and or vise grips. Prolly be a good idea to change the lines if the $ is available.

Good Luck!!

Yea, vise grips then replace the hard line if if you damge it

I rounded the hard line off pretty much and i dont think it was gonna move anyways. Im going to get a new hard line and take the new rubber line i have and change those eventually. Thanks for the help guys. I finally got it put back together
