Alternater bracket suggestions

[70 longbed]

I put vortec heads on my block w/roller tip rockers and posi locks. The problem is the stock valve cover didn't fit so I bought adapters to use my ball milled aluminum covers. The new issue is the alternater bracket is not long enough now. The only long one I can find is a 14" chrome flat bracket and subsequently does not have the offsets to bolt up properly.

Is my only option to bend the chrome one, or does someone know of a longer bracket I can use?

On a thread in the parts board it was mentioned that the 72 adjuster arm was the same as the 69-70 arm, just longer.

Can anyone verify the 72 arm has the offset bends in and longer and if so, by how much?

Thanks

Im the one that says the 72 arm is longer, which it is. Let me see if I have a pic on my computer with it installed. Here you go. The straight part is longer and it has slightly more adjustment then the 69-71 bracket. You should be able to tell from these pics if it will work for you. Hope this helps.

Thanks.

I agree it looks longer than what I have and that is where it bolts up.

Now the search is on.

I bought a chrome one and put some bends in it, but the arc is different and the bottom of the adjuster arm is real close to the fins on the alternator.

Does anyone have a 72 alternater adjusting arm they will part with?

I was thinking of putting Vortec heads on the motor I'm going to build. Is the reason the alternator bracket doesn't work because of the valve covers, or the heads themselves?

The issue with the vortec heads is the posi-locks I used on the roller tip rockers. The valve cover was not tall enough, and the posi-locks hit. I either had to go with a taller valve cover or use my non center bolt ball milled covers for the older the older style heads. The older covers require an adapter to fit center bolt to edge bolt pattern. That raises the valve cover and the adjusting arm did not have enough adjustment in it to get the valve cover on.

Solution is:
1) Try an adjuster arm from a 72.
2) Buy a flat adjuster arm (Checker or wherever) and put the necessary offset bends in it. (There were issues here as well, as the arc is not correct, so I had to grind some of the arm away to clear the fins on the alternator.)
3) Use a combination of the shorter arm and another adjuster bracket and weld them to make a longer arm.
