I am wrinting this question here because I am sure there at least a hundred forum users who have already crossed this bridge. The alternator in my non A/C '66 327 coupe mounts to the left (drivers) side exhaust manifold. What alternator mounting bracket do I need to allow me to remove the cast manifolds and install headers? There has to be something out there that is ready to go!

Thanks for any help that anyone can provide.

Some of the Corvette houses I’m sure could help you if you was to call them, but if it was me I would look into this.

If you have mounting holes in the front of the head the stock Vette/pickup bracket works nicely.

For stock heads without accessory holes drilled, use these:

Yes, that is the place to go and all parts are in stock.

People just love those extended brackets that make mounting soooo much easier.

This is a Chinese POS and the very reason I developed the Header Power Bracket.

Thank you to everyone who replied. My heads do not have accessory holes in the end so none of those brackets work. After looking at what was available on line I designed my own today. It effectively replicates the iron manifold bolt points so the existing bracket can bolt to it just like stock. It uses the header bolt holes for cylinder #1 as the attachment point. I made a wood and card board mockup today and it fit just as expected. Tomorrow I will buy some 1/4" steel plate and make it for real. I will post a photo of my bracket here when I get it done.

Update: It's all done in steel. I fit checked it and it works just fine, then I took it off so I could paint it. The thru holes bolt to the exhaust port of cylinder #1. The holes in the end are tapped 3/8 - 16UNC and replicate the position of the threaded holes in the end of the stock left side rams horn exhaust manifold so the alternator and adjusting bracket, bolt on just like the factory part. This is simple and much more compact than what I could find online which tend to be more "universal" in nature so they are larger with slotted holes for adjustability, which I can understand from the manufacturers point of view. Thanks again to all who provided input.
