Just because you've got a vintage Flathead Ford V8 in your ride doesn't mean you're stuck with the antiquated charging system. Switching to a tried-and-true GM 1-wire alternator is a great upgrade for any Flathead-equipped vehicle with a 12-volt electrical system.
- Bracket fits 1946-1953 V-8 engines
- Heavy-duty steel construction w/ chrome plating
- Designed to work with the two narrow-belt drive system typical of late '50-'53 Ford/Mercury passenger cars
- Will not work with single wide belts unless the alternator is modified (see Notes)
Application
- 1946-1953 Flathead Ford V-8 engines with narrow two-belt drive systems
- Can be used with wide single-belt configurations with some modification
- Must use different fan bracket on some 1945-1948 applications

Quality-wise, the product is highly rated by users, described as a well-crafted bracket and plenty heavy-duty for mounting a GM alternator.

Mine is a work in progress. The parts I purchased from Speedway are mounted, look great, and are ready to go. The 'go' part is sometime in the future?

This is as nice a product as I have seen, and the instructions for modifications for proper alternator fit that come with the bracket are spot on. However, I bought this along with the optional wider "truck" pulley,with intentions of using this with the truck style water pumps and crank pulley. I also used the wider truck application fan hub. Be advised, the stock belts won't fit! I finally went to my local auto parts supplier and got a selection of differing length belts, and played around with them to get a set that would work. A lot of fartin' around, but I'm very pleased with the result. My rating is for the quality of the part and instructions. Just wish there was some sort of notice in the listing about belt fitment issues.

Good Product.

This bracket is plenty heavy duty for mounting a GM alternator. Be advised the holes are threaded 7/16 x 14tpi, so the original bolts on your generator mount likely won't fit. You'll need to source new bolts. I picked up some stainless bolts locally. Before you buy this bracket, make sure you do not intend to mount an A/C compressor. If you will want to upgrade to A/C, there are brackets available that mount the alternator and compressor side by side, and this bracket would be made useless. If you only want to mount the alternator, this bracket is a good value.

I found that the single wide belt was to short after installing and aligning alt.Now I am haveing trouble finding a longer belt to fit. I replaced the two stock water pumps with speedway pumps (wide belt pullie stock type) intending to keep a single wide belt. Do you sell a longer belt that will fit the gm alt system?

I have a 49 ford with a flathead and I have two belts. One is 5/8" and the other 3/4". Will I have to modify this bracket or will it just bolt on? The notes confused me because they say 2 narrow belts. Thanks in advance.
