2 Bolt Alternator Bracket Questions

[Eomund]

So I've dropped in an L20b into my truck but I only have the 2 bolt bracket. I've had..... some problems with it. One bolt actually broke even, which I will try to easy out this weekend.

 

Is there a way to make it more secure? I'm trying to get my hands on a 3 bolt mount but am coming up goose egg right now, so I'm looking for alternative solutions.

 

And help is much appreciated. Thanks!

I get a small punch and tap around the bolt on a CCW direction and hopefully it will rotate out if not rusted in.

then try drilling and EZ out but I wasn't good at it and the drill broke in the hole!!!!!!!

 Center punch to get exactly in the middle of the bolt so you can make the hole as large as possible without wandering into the threads. Think about it, a 1/8" easy out will not work on a 1/2" diameter bolt. You would want something like 3/8" hole and a suitable easy out to match.

 

It will likely come right out easy enough because to snap off, it probably worked itself loose first. A tight bolt won't allow the mount any movement to cause fatigue in the bolt itself.

No I get that. And what I plan to do. But is there something I can do to mount the bracket more securely so the bolts don't work loose? That's where I'm having issues unfortunately.

The problem is there are 3 different brackets, if you want the top one in the photo below PM me as I have a couple of them, the middle bracket I believe is off a 1980 thru 82 Datsun 720 truck but I don't know for sure anymore as I forget things over time, the bottom one I have no clue where it came from, I wish I had a few more of them, that one I am keeping.

What alternator are you using?
