I'm getting ready to build a Polycarbonate spoiler for Chaos (98 GMC Sonoma). The dimensions are 10" X ~55" X 1/4".
My plan is to mount the bottom side with SS piano hinge mounted to inside top of tailgate (so I can fold it down inside the bed when not in use) and use 4 turnbuckle stye splitter rods to support the top. Will this be strong enough?
Also, I plan to mount the turnbuckles to the tailgate with 3/16" pop-rivets as their shear strength is 310# according to Mcmaster Carr.
Anyone see issues with that plan?
Thanks in advance.

Sounds great!
We did very similar for a bit in champcar. No issues with it whatsoever. Sounds like a solid plan.
Good to hear!
Any suggestions on spoiler angle? I've read they should be between 50 - 55 degrees...

From what I understand, it depends on what is in front of it. Like if it is a flat area in front of it, you want a steeper angle versus say a sloping hatch.
It's adjustable though, so play with it and figure out what works best in your application!

Since it is a truck and you did not specify if the bed is covered or not, here is my advice on angle:
Covered bed - run a straight edge or string from the top of the cab to the base of the spoiler and set the angle to about 90deg with the straight edge.
Open bed - run it nearly vertical, maybe closer to 10 degrees back from vertical.

Awesome! Thanks for that info!
I'll post a picture of the truck when it's back on the ground and with said spoiler and front splitter installed.
