Bowtie Truck Stop is proud to offer new 1972 Extreme Bend tow hooks. One of the hardest parts to find today because they were only offered during the last half of the 1972 model year. 1972 Extreme Bend tow hooks are now available. Made in the USA with the same grade and hardness steel as OE. These will look amazing on the front of your K5, K10, K20 or anything else you want to bolt them to. $625/pair delivered US.
