Q & A

What's in the Box

These low mount alternator brackets mount common Delco alternators below the frost plug at the left front corner (driver's side) of your small block Chevy using bolt holes next to the timing cover. They are ideal for custom builds, street rods, and tube chassis cars that do not have power steering and work with short ('55-'68 S/B Chevy) water pumps. These brackets will support a standard full-size GM alternator which is sold separately.  Includes bracket, bolts and spacers. 

  • Mounts common Delco alternators below frost plug
  • Left front corner (driver's side) of engine
  • Bolt holes next to the timing cover
  • Includes bracket, bolts and spacers
  • For:
    • small block Chevy
    • 1955-1968 short water pumps

Note: Watch for steering box clearance!

Notes

  1. Mounts alternator down beside oil pan, using early front motor mount holes.
  2. This bracket will NOT work with Speedway's T-bucket kits because the frames are too narrow.
  3. Not designed for use with standard (stock) engine crossmembers - will require modification to allow clearance.

Sorry we do not have a belt length for this alternator bracket. Length will vary depending upon your pulley sizes so you will need to measure for the proper length once you have the alternator in place. A rope works well to simulate the belt, then you can lay it out straight on the floor and measure the length.

what is the dim. from the top mtg. hole down to the bottom of the bracket? I see the width is aprox. 6.4" to 7.3 " wide but I don't see a measurement for the total height ! I am not if it will clear my steering rods!! Thanks Ron

This alternator bracket is designed for the hot rod enthusiast to mount the alternator down low and out of sight. It will not work with most muscle cars and the equivalent as the cross member and steering components share a lot of the same space required by this bracket and the alternator it retains. There is an alternator bracket illustration on our website that shows the location as follows: From the centerline of the two holes directly above the pan rail on the drivers side of the engine the alternator will position outward towards the drivers side front wheel about 6.4-7.3 inches and the bottom of the alternator will be approximately in line with the bottom of the front of the pan.
