The 73-80 shackle bracket provides a solid mount to your classic square body truck!
Bolts up to stock holes in 73-80 4x4 GM truck, Blazer, Suburban, and Crew Cab frames - also fits 2wd trucks - but may require drilling.
Installation is simple - bolt the Engineered Vintage Shackle Bracket to frame and you have two solid front tow points protruding from underneath the stock bumper for pulling / vehicle recovery.
The Engineered Vintage Shackle Bracket bolts to the frame and provides a solid front tow point underneath the stock bumper for pulling / vehicle recovery while not compromising front bumper or frame looks or integrity.
73-80 GM Shackle Brackets each attach with (3) grade 8 bolts & accept a Shackle / Clevis with up to a 7/8" pin diameter.
Some trucks that do not have factory tow hook holes may require drilling 1/2” diameter holes in frame.
