All good points, Hillbilly Heaven
In the 78 there is a rocker bar, I have the seats mounted to this as well (would look like a # from above) So the added "seat" bar will be attached in that manner, from the rocker bar up to somewhere on the main hoop behind seats. I agree on going further up for the shoulder, but ease of entry maybe different on that car the picture is from. I also want to run brace from where ever the shoulder bar is to the a lower point on the rear bar. This will support the main hoop better and also the seat bar. I do not currently have enough front to back support, at least not in my opinion. I will try to get pictures from sides and maybe some paint doodles too, of what I am thinking.
Though this is close, I stole this from the go-fast website. If the red bars went up higher, then had another support from that to the Diagnal brace, with a gusset between them.
Another reason I want to do a lower dash or "knee" bar is it will give me a good spot to build a new center console from eventually, once I get a few more things sorted out. I also thought be good spot for phone houlster and maybe some other stuff, like a Sat. Radio player thingy.
Will likely make more sense with newer pictures of the current setup. What I have is close, just not done yet to what I think I will be doing with the truck once the new engine goes in. These things are why that engine is not in it yet too.
