well I have been having clutch problems that came to a head monday when I found the ball stud broken off in block for cross linkage. my problem is getting threads out of block. went thru 17 various bits today and did not make a dent in pc in block. Of course there is nothing to weld on or chip at to try and get it to turn. Gonna need some sort of hardened bit to drill hole for extractor to work/ check out pic. anyone know of GOOD bits?
Thanks Tony

A way around this might be as follows. There are (were?) bolt on brackets that provided a mounting point for the pivot stud. One of the big performance dealers in Texas (Scogging DIckie?) sold them for use on some BBC's that did not have a pivot mounting boss in the block. Gen 5 BBC's maybe???? Anyway the bracket mounts to the bellhousing and positions the stud in the correct, stock position. Cannot for the life of me recall what the thing is called but it just might be an answer to your situaton.
Post #2 & #4 Center punch, actual drilling oil, slow speed using a variable speed drill and pressure. Start with a small diameter drill. The center should be softer. Then step up drill size. Drills must be sharp.

Something like this might allow you to blow off the drilling. THis is not exactly what Scoggin Dickey offered but might help ya visualize what I am talking about.

Great Ideas, one more of my problems is getting enough room to center punch bolt. I tried short 16d Nail and a pc of angle iron but that would not leave a mark. not enough power. In worst case I will look into bracket. at lease all is not lost. thanks tony
I ordered the Scoggins dickey bracket to make show (watch it rain) but I will try a cobalt bit and I have the reverse bit so If I can get a starter hole I should get lucky (fingers crossed) In any case the members came through again like always with great ideas and help. Thanks all!!! I will let you know how I make out. Tony
Cobalt will not work well but you can try. Carbide is by far the best for drilling hardened bolts. Find a left hand it and it should spin out. Also mig welding a nut to it may help if it is not too deep.
That happened to me. The mistake I made was trying to remove the stub with an electric drill set to turn clockwise. It ran the stub all the way through. The stub ended up in the bellhousing. No fun getting it out of there. You need a reverse twist bit. Start with a small size. If you are lucky, the bit will bite into the stub and back it out of the hole.
The likely reason the pivot ball broke in the first place was that it worked itself loose and backed itself out of the mounting hole. When you reassemble, use the highest grade thread locker to make sure the pivot ball stays put. It will be tough if you have to remove the pivot ball. That is a better problem than having your clutch linkage fall apart because the pivot ball broke.
If I had it to do over again, hydraulic may have been a better choice than the OEM set up.
