One of the first things I did when I purchased my 1960 Vette in 1983 was convert it from a generator to an alternator.

I placed the alternator on the drivers side.
And I'm still using the original type engine mount.

However I've never been quite pleased with the set up. Now that I'm starting to get some of my energy back from Mom's passing in December and my cancer surgery in March, I'd like to tackle a few things on the Vette.

Can someone recommend brackets or a mounting kit to adapt an alternator to the driver's side on a C1?

Thanks kindly

If you run headers, try a Header Power Bracket.

No headers. using ram horn exhausts....

thanks

Thanks kindly Bill

From your link I found these...




side bracket


The vendor claims they work with the original engine support.

Anyone here using these? I ask as they are a tad pricey at $90.00

Thanks kindly

that's basically what i'm using...

you might check the a/c kit suppliers for what they are using/selling; may be a better price, or not...

With a couple small spacers, this,



will do the same thing as that at about half the cost, (including an "F" bracket) and give you more front/rear adjustability to get the belt aligned. It becomes a matter of how much you want to spend and which shape you prefer.

Both left and right sides are covered.

Bill do you know if these will work with the ram horn exhausts?

Ken,

Bill has ram horn exhausts.

Doesn't matter if they are rams horns or headers.

The bolt holes are in the same place. But with rams horns the spacers would be shorter because they only need to be long enough to mate the "plate" from the outside edge of the exhaust manifold to the indentation in the exhaust manifold where the bolt heads sit rather than all the way down to the header flange.

Either type of mount on a ram's horn is going to look a bit funky and if I intended to keep ram's horns, I would get the reproductions with integral mounts as GM did it back in the day.

But there is that cost.

wmf62

dunno, doesn't look that 'funky' to me... besides, if you were to use a/c there is no other alternative than 'funky', so you might as well have matching 'funk'
Bill

You're right. It's hardly noticable.

The OP has some options.

Bill - car looks great... Still loving the ifs you installed a couple of years back?

Cheers

I phoned Alan Grove and they informed me 213L SC is the bracket I require (alternator on the drivers side)... He did say they will only work with the earlier ram horns which have an exhaust diameter of 2 inches and not the later ram horns which have a diameter of 2 1/2 inches. He asked me to measure the diameter where the manifold connects to the exhaust pipe.

It measures 2 1/2 inches...

I'm really disappointed...

Any other recommendations?

My present setup. Ram horn of drivers side is the later ram horn with the alternator mount on the ram horn... The adjustment bracket is the original which has been shortened a bit...

These photos are a few years old. Since then I've added a small spacer between the ram horn bracket...

kenmo

The alternator needs to be more secure as it is prone to a slight twist...

PS: kid brother aged 55 and all his life a mechanic thinks we maybe able to adapt the Alan Grove front bracket and and not use the side bracket and instead use the existing ram horn bracket already on my car... Anyone care to comment...

As I noted, if you use the correct sized spacers, you can use a Header Power Bracket.

I pulled a manifold out of the loft and here's what I mean. This is an extended left side bracket on a manifold shown with a 1" spacer in front and a ~1/2" spacer in back. I'm betting that the #3 and #4 bolts are 1/2" longer than the #1, #2, #5, and #6 also.)

You actually could use a 3/4" spacer in front and a 1/4" spacer in the rear if you grind just a bit off of the back edge of the bracket to fit within the contour of the manifold a bit better.

If you are worried about twisting, these are full 1/4" American steel all CNC cut.





Of course you don't need the extened bracket and could use a standard bracket. Then you need two 3/4" spacers (shown here with 1" spacers).

Plasticman

Ken,

I should of stated earlier that Bill (wmf62) has 2-1/2" ram horns (relativly recent aftermarket copies).

So what ever he used, should fit yours.

Toddalin's bracket look like it would work as well to mount it to the manifold, but you still need the brackets that hold the alternator.

wait a sec, my manifolds are 2-1/2 inch and the brackets came from Alan Grove.

and, i don't see where exhaust pipe size would make a difference...

here's the instructions that came with it:

Yes, you still would need the "F" bracket, but they are cheap (often under $10) and plentyful on ebay (and everywhere else). Be sure that you get an "F" bracket that cinches the alternator forward with a spacer that clamps forward when you tighten the nut.

I have Allen Grove brackets on my car. Yes they work with the original motor mount. I have headers also. I did have to grind some of the original left and right side motor mount supports to give the belts some clearance, because they are so far out to the sides.

P.S. the belt sizes recommended did not fit. I had to try a few times to get it correct.
