What are you guys using to replace the generator bracket to fit an alternator?

I just started trying to build or find a bracket that will work but i thought i better ask you guys what you have found to work.

thanks for any info.

    Stepdown? I took my generator bracket and turned the mounting holes into slots on the mill, then mounted the alternator, GM 10SI, ('outside' the bracket) with a long piece of all-thread and a long spacer made of 1/2" tube through the whole bracket. Pretty rigid, but would be improved with another brace from the back of the alternator to the rear of the bracket. I used the stock upper bracket and made a little spacer bracket for adjustment. You might be able to see it in some of the pictures on my profile page.

    Walt Mordenti sells alternator brackets for Hudsons. I have one on my 53 Hornet.

    GrimGreaser,
    Can you post a picture of the bracket? I was wondering the same thing, but was planning to go with a 12SI model.

    I did the same thing as grimgreaser did I used the stock brackets, and by using spacers and washers I was able to mount the alternator. The generator can replaced
    anytime for originality.

    At the Twin-H-Ranch, we use the original and slot the holes then take another bracket and cut off the rear of it, use alt mtg to check length, lay it inside first brkt weld together and drill holes to mount to block and hole to mount alt.

    I got it, I used a piece of threaded rod, a couple of nuts and washers, I think I had to flip the original bracket around. I had a metal pipe for the inside of the original bracket to strengthen the bracket but it was too big and hit the bolts that bolt the bracket to the block. (will keep looking for a smaller diameter pipe)

    attached are some pix, since the pics I cut the access threaded rod off and painted it.

    Thanks for the pics guys. This should be an easy winter project.

    I know a lot of guys are using the GM single wire alternator, but when I changed my '54 coupe to 12 volts I found a complete '70 mustang that was going to the crusher and transfered the alternator and voltage regulator to the Hudson. I made my bracket in much the same way Rich did and had no troubles for over 2 years. The coupe is now down for a complete rebuild, with a Camaro subframe and a small block (NOT CHEVY) maybe Dodge or Ford, PS PW PDB, Maybe even shave the door handles.

    I've just been through the alternator exercise. I used a new 60A Bosch alternator which are very common and quite cheap down here and also have an ignition light connection. It came with one of those new fangled multi groove pulleys, so I made an aluminium B section pulley the same diameter as the generator pulley to replace it.

    I thought about reworking the original mount then figured it was just as easy and also a better job to cut up some 1" flat and make exactly was needed.

    This is my shiny new alternator with its shiny new pulley waiting to be installed in my not so shiny engine bay.

    I installed a 12 vlt gennie from a 56 Buick along with the voltage reg,13.4 volts output .Looks factory except for the battery.if stock appearance is of no concern, other than availability ,is an alternator superior to gennie J.R.

    The Main Difference is that the Alternator starts charging at a much lower RPMs than the Generator. More over the alternator is more compact. I ran a 1970 mustang alternator with the mustang voltage regulator on my 1954 Hornet coupe for over 2 years and had no problems at all.

    Use the smallest pulley you can get, as you will have to race the motor to get it to start charging, and at idle it will not charge. Alternators charge even at idle, that's the good feature. I'm on the 12th year with mine, replaced the first one at 70,000 miles and am up to 134,000 on the second one and still going strong. The belt line up is the whole secret. Even 10,000 off will knock out the bearing. You guys that have the radiator off your cars, set engine at top dead center, and make a pointer to bolt to the timing cover, file a groove in the counter balancer to line up with pointer, and now easy timing. Check out my 53 sometimes. Walt.
