Running Boards Installation Help

Ive got a 2010 Double Cab. I just picked up some running boards off of craigslist. They look like this:

But without that black piece running along the back side of it.

It came with 4 brackets marked BRK100-6-8-MR and 2 marked BRK100-6-8-F.

The installation seems obvious from looking under the car, but I'd feel better with some confirmation.

1) It looks like the brackets mount to the body with the bolts that have a flathead slot. Is this right?

2) F means Front, MR means mid and rear

3) The boards them selves have 6 bolts for mounting to the bracket, but it seems that i didnt get the nuts for them. What are the threads?

4) Do i need washers? Gastkets? Anything else?

5) There are plastic covers for the brackets. If there are washers or gaskets or whatever, where do they go relative to the bracket-board-plastic cover set up?

Thanks
Jeff

 

Pretty sure you won't need nuts. (at least for this job ) There should be tapped holes in the frame rails under the truck. Shouldn't need washers as long as the head of the screws are big enough diameter. Threads are M10 or M12. Do a search, this has been posted before (I remember being involved in a thread where someone stated the correct thread form).
Can't comment on the other questions as I've only installed 2 different sets of tube steps and one drill/screw set of rock sliders.

 

I can't comment on that paticular brand of running boards because I'm not familiar with them. I installed some Toyota OEM running boards and they mounted to the body (inside of of the rocker panels).

Look underneath your truck, you'll see round plastic plugs with slots in them. They look like round plastic screw heads (kinda). Remove them....
These are the holes you'll mount them to. The holes are threaded ( 8mmx1.25). YOu don't need any nuts. Just use the bolts they provided.

***Here is a picture of the placement of the holes under the truck (on my 07)**

 

look for plastic plugs in the body, not the frame. inside the plugs are threaded bolt holes

 

when i put mine on the brackets for the center support were labeled backwards.
