Give them back to him. T50 grade aluminum is mainly used in utensils, decorative trim, chemical tanks, and awnings because it is not heat treatable. Aluminum is stronger than steel in some aspects but it is also soft, therefore the stud often pulls loose from the knurl seats on the aluminum (especially if they are over 1" thick).
The only adapters I have seen for these trucks are steel and you have to reverse (invert) the factory lug studs for the hub bore of the wheel to clear the stock lug pattern. I am not a fan of this because it make them a pain in the a$$ to install and they are not user friendly.
We build direct bolt wheels for these trucks as a result of them being user friendly.
