That, a couple of short extensions and a couple of U-joints was the only way to get one of the bolts off.

Re: [MBZ] Rusty exhaust bolts.
Long time ago I learned that if you replace the good MB bolts and nuts with 5/16 'merkun bolts, the next time you need to do the job, the 'merkun bolts will twist off with 1/4 turn. Much faster. Rust up solid. Just a little turn, and they pop right off. Of course you have to have new bolts and nuts. It took me a few hours to remove the two bolts that attach the header pipe to the exhaust manifold. The first one came loose after mutiple penetrant applications- over a few days. The second was really stubborn- it was starting to come but ultimately snapped which is fine as the bolt just passes through the flanges- not threaded thru anything. Overall was a moderate PITA.

Re: [MBZ] Rusty exhaust bolts.
Coppers drive around in cars looking for trouble to inflict on the citizenry. Copper nuts are for 'merkun junk with mild steel studs in the exhaust manifold. The MB exhaust pipe nuts may have a plating on them, but every one I have seen is high grade steel (self locking), to match the high grade bolts used. (OM621 to OM603, and same vintage gassers) (1959-1989) DId it have the original copper nuts, or were they replaced with steel ones? I've been amazed at the ease of removing the copper nuts from bolts that I was sure would break. Not finger loose by any means, but no where near as hard as I expected due to the condition of the threads they were going over.
