Here is the same bracket on Ebay, I will get a pic when I get over to the shop.

WOW! That looks great. Can't wait to see how you used it and what you modified to make it work.

so you end up with two mounting holes that are used to secure the bracket to the front of the head? I think this would work just fine as long as the cheap Taiwan bracket itself doesn't implode 
Thanks for the heads up on this! I think I am going to get one to try it. I'd probably media blast it also and paint it black

Can you post a pic of the connection to the head please. From the driver side is where the big problem is for us.
Looks like it uses the two outer bolt holes in the front of the driver's side cylinder head. No mounting point on the exhaust port/header bolt :? This should work perfectly. I would be curious to know if you could mount the upper bracket on the left most bolt hole on the head...using all three bolt holes then to mount the alternator instead of using the water pump bolt like shown in the photo :? 
You are right, the piece that went to the BBC exhaust manifold is long gone. Two grade 8 bolts hold the bracket to the head. The upper bracket probably could have gone elsewhere, but it probably would have required a long(er) bolt and/or a spacer to line up with the alternator. BTW, the upper bracket is from Petepedlar and has since been powdercoated. This seemed to me to be the simplest arrangement.
Dave....can you post a picture of the Stahl headers you have. I'm sure it has the tab on the LH flange to mount a stock alternator bracket. I know the Doug Thorley headers we used to sell had the bracket. Bolt up the headers and attach the alternator or generator brackets.
I ordered one of the Taiwan brackets that Boxerdog posted and will modify mine the same. With my motor mocked up on the stand, I should be able to come up with a solution to mount the alternator. I will media blast my bracket as well and paint it most likely
Got the Taiwan bracket last night and am in the process of modifying it for use on the 409. Cut the tab off, re-drilled the hole to line up with the front of the cylinder head and lopped the bottom of the bracket off. Will radius the bottom portion on the bench grinder tonight, media blast it and paint it. A quick mock-up with an old alternator shows good belt alignment also
I need to get some hardware to really test it out but I think it should work great. I am using a top alternator bracket for a small block that Ross got for me from a salvage yard that seems to work good with the bends in it mounted to the third hole in the head but which places the slotted portion of the bracket on the front of the alternator...really close to the blades/pulley. This set up will work fine. I might want to try a cheap Mr. Gasket chinese top bracket to try mounting that to the water pump bolt to see if that might work even better. We'll see
I'll post photos also when mine is done and installed but this does seem to be a decent option for mounting an alternator on the 409 when using headers

The Stahl fenderwell headers I used on my '57 small block drag motor had a tab on the left header to mount an alternator. This was 36 years ago.
