Any solution for belt adjustment?

I'm sure I'm not the only one that has had an issue. The way you adjust the belts on these cars (alt and ac) there is a bolt you loosen and then you put a wrench on a cogged piece which rotates on another cogged piece. Well mine were rounded off since its so thin and rusty over time. Has anyone changed there's to a bolt that presses against something to pull it tight or something else? Can you replace these with new pieces? Right now I've just pried against the accessory tight with a pry bar and tighten the adjustment bolt.

Funny you mention this. Maybe it's different on the 40v V8s, do you have a pic of the tensioner on that? On the ABZ the tensioner pulley is on a sprung bracket that keeps tension on the belt. An ~8" shock absorber/damper looking thing bolts to the timing cover and to the tensioner pulley bracket. I ran the motor without the damper and I saw the tensioner moving and the belt tracked off. I then had my buddy hold a 13mm wrench on the tensioner to keep it tight and it seemed ok. The part from the dealer is over 200 bucks so I made a solid rigid bracket to hold things tight. Only downside to my design is that over time as the belt stretches I won't have the damper to auto tension the belt. I'd have to check it, and keep retightening it as it loosened up.
He's talking about the older 5cyl engines. It is a crappy solution only because of the metal they used. I used to use force on the body of the component with a pry bar, then just tightened the stuff down.

Thanks Golden but yeah I was talking about my 5 cylinder. Sorry I should have specified. It squeals 85% of the time when moving from a stop for 2-3 seconds then I won't hear it again unless I downshift or come to a stop and move again. I'll get under there and pry it again and tighten her up. Seems to loosen up after a while. I just don't like to keep fixing something if there is a better way to do it.
If your a/c isn't working ditch the a/c belt for one. Try a dayco top cog belt for the alt.
The A/c works but it has a leak so I need to re-charge it frequently. I'll try to get some dayco cog belts. Thank you.
Not going to help much when the bracket that has the other cogged end is also rounded off :/
Ah sorry. Thought you meant the bolt rounded out. I have a spare bracket somewhere where are you located?
Ah. I can look around for it and if you wanted to pay for shipping I could send it.
I'll keep that in mind, I'm going to see if I can do anything more on my end before I take you up on that. Thank you.
Other than that I'd say pry and tighten.... You'll have to tighten it every once in a while.
I didn't have good luck with TopCogs. I only had good luck with the Conti belts...
Found these a while ago while looking for alternators. I'd imagine it's the same for all the 5 cylinder tensioner brackets and whatnot. There's a bunch of listings for them if you search around.

Woops, nevermind. Just realized you meant the bracket was toast too...
