No, not quite.

Bolt 1 goes through hole 1 on the bracket, then through the alternator, then the upper hole (looks like #2 in your picture) on the manifold.

Hole 2 on the bracket is bolted to the lower hole on the manifold that you did not number.

The bolt that holds the water pump goes on the upper bolt just like the J-bar. This braket goes on first and the J-bar is on top of it, then the washer and bolt.

The included diagram from the '70 assembly manual should answer your questions. You'll have to be the judge on the motor mounts.

This will fit in a small box so I can ship to Canada and would add the difference to the price.

KENMO Do you think it'll clear stock C1 engine mounts?

PS: I'm in Canada....

toddalin I thought that it looked familiar so went up in the loft and looked around. This is the piece that you need. You can have it for $25 including the shipping in the Continental US.

You can see how it wedges the alternator between the manifold and the bracket at the upper hole while the lower hole bolts into the manifold to stabilize it. The other hole goes to the water pump bolt.

Actually, the way you currently have it, you've moved the alternator ~3/8" forward (thickness of the bracket) and outwards a bit from the stock arrangement because the bottom hole of the alternator should be in the upper manifold bolt hole. Hope this helps.

Yes, that's the one. I looked at my assembly manual and yes, a similar bracket was used on the '70 Corvette with the forward bolt holes.

toddalin There were a couple different manifolds with forward holes.

On a '65 Vette with A/C, there is a bracket that extends from the water pump and meets the lower hole of the manifold. The alternator is bolted to the manifold through the upper hole and the other bracket that extends from the water pump sits in front of the alternator wedging the base of the alternator between the bracket and manifold. A J-bar is used to tension the belt.

But the '65 Vette exhaust manifold has the top hole recessed from the bottom hole.

On manifolds with the holes as you show for the Impala, the engine typically uses the long water pump so the alternator sits further forward.

No Corvettes ever used the long water pump, but there may have been other year Corvettes that did find some way to use that manifold forward mount so check the assembly diagrams for the various years to see if you can find what will work. You may find that these other years that used that manifold had other brackets that used accessory bolt holes in the heads or on the intake manifold on the 350s.

I seem to remember having one wit hforward bolt holes and if I did it was for a Corvette and probably a '70. But it may have been a bit different.

cobalt327 The set up used on 'Vettes w/ramshorn exhaust looks like the image below, but if you don't have that manifold, just use the bracket like used from about '72-back on trucks w/ramshorns.

cobalt327 SBC pulleys and brackets.

toddalin You could use a Header Power Bracket with the appropriate spacers.

For an extended bracket:


or for a regular bracket:

68NovaSS Unless you're trying to keep it original, you could go aftermarket, ZOOPS has nice brackets for just about any accessory or application.

KENMO Can someone post an image of what the correct bracket looks like? Thanks kindly...
06-25-2012 06:04 PM
S10 Racer Yes you need to add the correct bracket to hold the alternator true to the crank. You are correct, there is a part of the bracket missing in the photo.

78 monte Yea most mounting brackets have a tang for the front of the pivot bolt. There were allot of differant brackets best bet is to either go to a U-Pull-It and hunt for something or buy a bracket kit. Or order the correct bracket from a vette parts supplier.
