Listing these under Datsun parts because they share the 5-lug bolt spacing. I cut these centers from a set of Jeep Wrangler rims. They might be useful for a set of custom homemade wheels, shop rollers, grinder stand base, robot dog frisbee, or whatever you like. Outside diameters measure roughly 14 1/8" and were pretty cleanly cut with a plasma cutter. They're pretty thick too. 3/16" - 1/4".
$20/set

When the only tool you have is a hammer every problem starts to look like a hippy.
