Or, fire. Heating them makes things a bunch easier. Plan on buying some new fasteners.

Or plan on buying new studs on the downpipes, too. I broke a couple of mine in the process. Don't forget the antisieze when you reinstall! My PO obviously did!

with two universal joints, a long extension, and a cordless impact wrench (or air ratchet) its pretty easy to those six nuts from under the car

Did you remove the heat shield? You should be able to get at the nuts with a straight socket extension. I cant remember if I took the wheel off too to give me room. Either way wear gloves cos when they let go you will bang your hand on the subframe
Edit: if you are driving a left kicker you may not have the heat shield. It protects the UJ on the steering

Here's an old trick my uncle taught me for siezed nuts n bolts. Get a nail punch (one with a flat end; ie. not a centre punch) and a hammer. Place the punch on the FLATS of the nuts and give it a few whacks with the hammer. Do it on as many flats as you can on the stuck nut, more the better.
And presto you'll be able to undo them with your wrench/ratchet.

A blow torch on the nuts till they are red hot always worked for me. You can also try tightening them, just until they actually give,before trying to loosen them. I suggest use some penetrant like PB Blaster or Mopar penetrant with graphite.
OK Head Off new one on.....blimey it works....now just got to flush all the crap out of the cooling system, then bleed it......i was advised to jack the front end up as much as i can, open the thermostat bleed screw and "rev the nuts off it".....is this a good idea?
Thanks for all the advice....universal joint was the clincher!
The whole job has played merry hell with my manicure!
