This alternator brace Is designed for mounting High Mount AC brackets from 1995 F-800/Freghtliner onto 1994-1998 Dodge 12 valve Cummins 6BT engines. We use this set-up in all of the 73-87 Chevy to Cummins 6bt conversions, it allows you to run a bigger Sanden AC compressor without notching the frame. Add on our tensioner mount in the options if you don't want to modify the Cummins part.
