Installation Notes: 

This transmission crossmember is designed for specific drivetrain positioning geometry that was engineered by Hooker Blackheart to work in combination with their product line of engine swap components. The use of any aftermarket equipment such as; engine mounting brackets, headers or exhaust that are not sold by Hooker Blackheart explicitly for custom swap applications is not advised and is not guaranteed to fit.

This transmission crossmember will not work with engine mounting brackets that move the engine or transmission away from the stock factory offset, or the mating plane away from the stock Ford small block fore/aft position. 

This transmission crossmember will not install in 1979-1981 Ford Mustang models without modification to the factory transmission crossmember receiver brackets.

If installing this crossmember in a Ford Mustang using a Ford Coyote engine and using a Powerglide transmission, a JW Performance bellhousing is required, but no transmission mount adapter is required.

If installing this crossmember in a Ford Mustang using a GM LS-series engine and using either a Powerglide, TH350 or TKO transmission, no transmission mount adapter is required.
