Anyone have a SWB fleet, 2WD leaf springs & rear sport bumper? Could use some help

[71CHEVYSHORTBED402]

I had another thread out there, but it was a mess and no responses, so starting over

My truck is a 2WD, SWB C-10 with rear leaf springs. For what it's worth, the truck had a factory step bumper. The sport bumper brackets I got read for 4x4, but the vendor says they're correct for 2WD as well. From here I don't see what they're for. It's the inner bracket that's the problem, I think all outer brackets are the same.

The images show where I'm at. Makes it difficult not having the right bolt pattern, but I think I'm on the right track. Any input appreciated, especially those with a SWB 2WD fleetside with leaf springs. GMC anyone? - I believe they're primarily leaf springs.


Other than that:

It would go a long way if someone could tell me the distance from the frame rail to the bumper mounting surface. I suspect it doesn't matter leaf spring or coil on a SWB. Seems a SWB 4x4 would be the same. Maybe even a LWB, because my C-20 has a similar bolt pattern used for a step bumper.

Strikes me the brackets for a coil spring truck may be a better option. Thank you.

Post 10 shows the brackets mounted. I think it's a SWB coil spring truck. It's mounted consistent with image 2 (bolt patterns A & B): http://67-72chevytrucks.com/vboard/s...d.php?t=488496

Some coil spring brackets. One is wrong, the holes in the brackets are supposed to face up for gravel guards, but it probably works without them. http://67-72chevytrucks.com/vboard/s...d.php?t=307775

This guy had the same issue as I d. Appears he ended up using the brackets for a coil spring truck. Post 3 is a mystery, he's using three bolts: http://67-72chevytrucks.com/vboard/s...d.php?t=634044

Same problem, and he ran with brackets for a coil spring truck as well: http://67-72chevytrucks.com/vboard/s...d.php?t=213260
