Correct drvs alt mounting brackets - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Would anyone have a pic of the correct mounting hardware for the drvs side V8 with the original manifolds?
The set I have is not correct. It hits the embossed section of the exhaust manifold. Asked a few members parting out trucks if they have any available but want to make sure this time I ask for the correct ones.

looks like its time for headers! j/k I'll take a look at mine today and get a few pictures for you (im not 100% sure mine are orig. but I know my alt uses that bracket)

thats the correct bracket so i'd think the problem is with your manifold not the bracket

In another pic I just looked at with the alternator mounted, it looks like the bottom mount is lower on the head than what your holding it. I haven't been outside to look at mine yet so that's all I'm going off of. The pic is in the parts section in the thread "69 c10 for sale".

Here is one looking down on it.

Front underside looking at it.

Close up. You can see I made some spacers for it. This was to align the pulleys though not to clear the exhuast.

From behind it.

The bracket you show on your post is a 69-72 alt bracket. You'll have to switch to 69-72 exhaust manifold to use it. Here is a picture of the 67-68 bracket that uses the bosses on the manifold:

I hope this helps.
