Roll Bar
I'm working on a roll bar design. I have two daughters that I am excited to drive to the local pool/soccer games in my truck and there is just something about having nothing over their heads that is spooking the dad in me.
I've got 2x3x1/4" HSS that I'm fabricating the bar out of. I'm using a 1989 Dodge Dakota like the one in the attached photo as inspiration. This isn't a cage, just a loop to help keep the truck off the ground if it ever rolled somehow in an on-street accident. I'm planning to wrap the roll bar in sheet metal and create a hard top that is removable like a lid (think ferrari) so that the windshield can still fold down.
I have a hole cut in the floor to pass the HSS through so I can mount it to the frame and I've been trying to devise a way to connect to the frame that won't transmit vibrations and will allow some flex so it doesnt hit the inside of the sheet metal surround.
My best idea at the moment is a bushing with 9/16" Grade 9 bolt. I ran some numbers and the bolt wont be the weak point. I like this bushing in 3":

See attached sketch I did to mock it up.
I'm looking for feedback. I'm absolutely overthinking this but thats what I do! I'm wondering if anyone sees a problem with my idea or an easier way to achieve this?
