most torsion bars ure under the least tension when fully open and have one bar facing right and one left
insert the fixed end in the bracket then with a suitable tool twist the end of the bar down as you put it in the hinge bracket repeat for the opposite bar
It is not easy until you get the idea as to how to twist the bar as you put it in place

See here p55. You will need to cobble up a tool which hooks on the bar, somehow.

Toyota refers to a special tool, see here p55

You can see how it works. I think an effective substitute could be mad from a length of hardwood with a dowel rod through it at right angles

one of those bars come out of its bracket ( on my 89 cougar)
none of the local shops would touch it, no even the body shops.
so i just connect one end to the lid, like normal, then with a pry bar, pryed out the other end and put in a small block of wood (two by four) then released the pry bar. took another bite pryed it out again then added another block until i got the desired spring back into the torsion rod. yes that's (jury rigged) but my trunk works almost like it should. if you need i can send you a picture of what i did.
