1st and 2nd gen runner maybe, but I can only see two possible holes on my '81 pickup which look like they'll be close (the ones in the end of the rails), AFAIK my factory bumper mounts along the rails not vertically off the crossmember?
That or I'm going blind
Anyone able to get a measurement across the centres for the two outermost holes on a 2nd gen pickup/1st gen runner so I can compare?
If the spacing is the same I reckon I could build some plate brackets to run back to the factory bumper mounts.
