All of the header/alternator mounts are garbage. They are stamped steel and flex like an accordion throwing the alternator out of alignment. Here's one I had modified, but it still accordions.




This next one looks good, but it is more or less a one-off.

Can anyone make a similar part and if so how much would it cost me? Seems like the market should be there for those wanting to replace their existing header mounts, all of which are garbage. Thanks

 

 

Is the one on the bottom of this page the same one you have?

Yes, they are all similar to that. The best looking of the bunch is the one sold by Corvette Central that at least conforms to the shape of the exhaust header affording a bit of extra metal and support. Also note that the lower bend goes all the way across, even over the header pipe. All of the others basically have their bends to the sides of the header pipe, so there is no support directly above the pipe as there is on the Corvette Central piece. But they charge $67 for theirs and it's still a stamped piece.

All the Other Crap

 

Shoot me a pm and remind me..

Friend made one for my 67 'El yrs ago nice stout piece never flexed and cleared the headers. Pretty sure I still have it.

Went through the same thing yrs ago all those stamped/chrome pieces either dont fit, break or plain suck.

 

You're out in Chatsworth? Is your friend Tim Moore (Tim Moore Auto) in the Sun Valley area? He made the "one off" in the picture.

 

Still looking for someone who can make this.

BTW, if you only think this will be a "one off," there is a very real business oppurtunity here.

Though you may think that these are really no longer used, just do a search on ebay for "header bracket" to see how many companies are still manufacturing and selling the old garbage brackets.

The market needs a better alternative.

Thanks

He can make you what you need.

Not sure if moore is around.
Yes, still in Chatsworth

 

Thanks,

I spoke with Moore a week ago. He said that maybe he'll think about making some around the end/first of the year.

Also an an alternative, I put the word out to our Corvette Club. A member's son-in-law works in NASCAR (in the Deep South) and said that he could probably make it out of stainless if I did a mock-up.

 

I found a machining facility that will make the plate to my specs, and can weld nuts or standoffs in the appropriate places, based on an example/model that I would supply. It would be on the order of $30 for one, but the cost would be reduced for multiple units.

Is this something that would interest you and if so, how much would you be wiling to pay?

If you saw this on the aftermarket, how much should something like this cost?

Thanks

 

OK, I've completed the design of the new header bracket and sent it off to be plasma cut out of 1/4" steel plate. I've determined that using the plate, if properly sized, no welding is necessary and the use of standoffs may be all that would be required if you wanted to move the alternator further outboard to use your existing belt. The nuts that hold the lower alternator bracket to the header bracket will sit in the recess created at the base of the valve covers just above the gaskets where they contour inward.

It actually looks like the lower alternator mounting bracket can attach right to this bracket pulling the alternator inboard and shortening up the belt without the need for a spacer. (But I'll probably put a spacer in to maintain my existing Gilmer belt rather than change it ($$$)).

Anyway, I've included the drawing. I designed it to fit snuggly around Doug Thorley Headers that are just under 1.7" external diameter. If your headers are bigger, the bracket can easily be changed to accomodate them.

If anyone else wants one of these, NOW IS THE TIME TO SPEAK UP!

 

Yesterday I spoke with the firm that will CNC plasma cut these out of 1/4" plate steel. There were a couple modifications to this design in that all of the 3/4" diameter (not radius) curves have now been changed to 0.85" diameter. This will place the tip of the "nose" and bottom of the top curve at the back end exactly in line with the slots and give a slightly more gentle radius making it look a bit nicer. He'll make up a demo and send it out to me next week to check fitment. If all goes well, they can knock these out in no time flat.

As it stands my cost in small quantities will be ~$22-23/each including shipping to me. I would like to get $25 a piece plus whatever shipping is to you. I'll probably use "if it fits, it ships" so you can figure the price accordingly.

If we can get enough people to commit, we can get a better price and I would pass the saving on to CF members. I'll probably have a couple extras made to take around to the local speed shops to see if they have any interest. I'll post a picture of the "mule" when I receive it. So, if you want one, I need to know ASAP.

Thanks guys.

 

These guys move their tails. They sent me the CAD drawings for approval today and will cut it out today/tomorrow.

I'll get some pics when I receive it. If you want one, don't take long to think about it.

Thanks

 

if you keep having trouble with the plasma guys, i can cut from my laser at work @.005 tol from 1/4" steel plate

one for 50 bux shipped or 10 for 100 shipped based on your drawing w. no bends

i can do pretty much anything with sheet metal so lmk.

 

Thanks, they think they have it and are sending a sample. If it doesn't work out, I'll keep you in mind.

There have been some revisions since the initial drawing (Originally, it may have difficult to get the bolts in without some clearancing), but the plate remains flat. Also,I am also thinking of bringing out an aluminum spacer that would attach to the plate to move the alternator back out to where the other brackets locate it so people don't have to change to a shorter belt. This could be polished to a high luster for a bit of "bling" if desired.

On another note, I am working on a totally new design made out of billet aluminum. This would be a two-piece design that would include both the header bracket and the alternator's "sliding" bracket. All of the current "sliding" brackets place the forward bolt under the alternator making it hard to get a wrench on. My design uses Allen keys that ride in slots below the alternator attachment leaving them accessable with the alternator mounted in place. The header bracket would be threaded to receive the Allen keys.

Initial costs are estimated at ~$1,000 for R & D, tooling, and to make the first 10 units. This does not include the polishing. I recognize that this may be a bit pricey, but there is absolutely nothing like it on the market, nor is there likely to be.
