Hey Ford builders! If you're working on a Small Block Ford 289 or 302 and want to run a GM one-wire alternator, this Chap Performance bracket is exactly what you need. Machined right here in the USA from solid 1/2 inch 6061-t6 aluminum, this thing is built to last. It works with the 4-bolt factory dampener and fits GM one-wire alternators that measure 6.6 inches (168mm) between the center holes. Perfect for 1969 1/2 or newer small block Ford engines with mechanical water pumps that have the driver side lower radiator hose. Just a heads up - you will need to drill out the 3/8 inch hole in your alternator to fit a 7/16 inch screw to bolt it to the engine head. Comes with all the hardware and instructions you need for installation (alternator not included though). The quality is seriously impressive - way better than cheap overseas copies. Whether you're building a street machine, resto-mod, or just need a reliable alternator setup, this bracket makes the GM alternator conversion super straightforward. No more messing with sketchy universal brackets that never fit right!
