need help! 1969 gtx 440 alternator mounting

[kiwigtx]

If the hole is deep enough, you can tap it for a thread repair insert (forgot what it is called).

Helicoil insert.

I think I am going to switch my heads around... ugh!

That will be the easiest solution.

I had an alternator bolt snap once....a bit inconvenient when over 50 miles from home. Bandaged it up using a socket for a spacer...has enough tension on the belt to drive home.

Swapping heads isn't that easy. How many hours and how much money does that cost? And what if another bolt breaks somewhere?

If you can't remove the broken bolt then pay someone to come over and do it for you.

Thanks Don, it looks like one of those small dish plugs. I'd try tapping on the side with a small punch and tilting it , and pry out..View attachment 1758272View attachment 1758274

This or maybe drill a hole in the center and use an easy out to back it out if it is sitting in the threads. The hole you need is still there, just need to remove the plug and helicoil if the threads are hosed up.

This does not appear to be a broken bolt. No one stamps a broken bolt with a number (P8C).

That bracket is for B blocks only, it won't fit on an RB block. The bolt is lines up to thread into the cylinder head on an RB block.

The alternator bracket is the same for both blocks on AC, on non AC the alt bracket has two holes for the alt bolt, B or RB block.

But both B and RB share the same big block heads go why b block only?

Lower deck height on the B block, so the bracket puts the hole up by the difference.

It looks like a disc plug to me also. Drill/punch a hole in the center of the plug, and use a dent puller to remove it. I also notice that the hole looks larger in diameter than the one below it, so it might already be drilled (correctly or incorrectly), and that might be the reason for the plug. A Heli-Coil will not work if the hole has been made larger. The proper repair when the hole is larger, is to use a "Big-Sert" (Timesert) which allows the larger hole to be repaired and bring an oversize hole back to the original size. The head looks to be already worked on due to the heat tab which shops put on to indicate an overheat condition and allay any claims of poor workmanship (aka CYA). Also, the big circular gouge tells me the bolt was loose and caused damage likely requiring the larger hole.

Drill a small hole in it. Determine its thickness. If its a core plug, pull it out with a slide hammer.

If space permitting, drill and tread a small maybe 1/4-20 bolt in and it’ll push out

Yes, now that the picture is opening there is no broken bolt.... There probably was a broken bolt but a failed repair has created a mess... It should have been an easy repair, but at this point I agree swap the heads around or use a timesert...
