Top Mounting Bracket

Now that you've got the bottom bracket finished and the alternator mounted to it, you'll find that the original top bracket doesn't fit. So head on down to you favorite auto parts store and get one of those big arched chrome after-market brackets made for GM cars. I found mine at Auto Zone for $10.

One thing I was glad about was that the stock fan belt fit just fine. That was a concern of mine as I don't have sufficient clearance between the steering rack and pulley to remove the belt. I was prepared to loosen the engine mounts and jack the engine up, but.......... I don't have to!!

Click on any picture for a full size picture. All the full sized pictures are about 75 - 100K in size.

Here's what the bracket looks like when purchased.... not really but you get the idea. You can see the original chrome section on the left and where I've cut it to size.

This shows the the bracket with all the chrome sanded off in need of new paint.

Here's a view from  the back. As you can see, the electrical connections are temporary for testing purposes and a test drive. They'll all get changed out when I install Dan Masters' wiring harness.

So basically that's it. My volt gauge is now pegged over close to 15 volts regardless of what I have running. I put my multi-meter on both of the output terminals and getting a steady 14.5 volts at the alternator. Now that this is complete it's time to start installation of the new wiring harness and power block.
