Stupidity, snapped two bolts on 85 200s

OH ok cool, I guess they are all the same size for the front axles. I have a 250es...I'm sure they're the same.

ok, its either one of these two numbers

90031969680 or 92900060250E

one is for the front fork stud and one is for the engine/exhaust header stud.

Dude be very careful here

What you need to do at this time is drill a hole in the stud and use an easy out to remove it.First soak with lots of penetrant for at least a day. Very carefully get a tiny drill to start a hole exactly centered on the stud. The act of drilling a hole in a stud allows the stud to shrink a little. Then if you can, insert an e-z out and twist it out. If you have to, drill it a little larger. Be sure to miss the threads, take your time! Be sure your drill bits are brand new, you want to take every advantage you can. If you think it will help, use a center punch to start your first drill pass. Use a little oil when you drill. Another trick is to heat up the whole cylinder with a hair dryer and use ice or freeze spray to try and shrink the stud. That works better on the larger studs, though. But that's going overboard, maybe not if it saves you a cylinder. When you get the stud out, chase it with a tap before you put a new stud in. GOOD LUCK

thank you very much, im sure im going to need all the luck ing the world. What kinda of drill bits would work best for this? How hard is the cylinder head to take off? The dealer said he would take care of it for me, only if i take him just the cylinder head, and nothing else.
