Any chassis guys here? working on mocking up a 10 pt cage for my 70 challenger. The car is going to have a caltracs mono leaf with assassin sliders. Wondering where the best spot for the trunk bars of the cage to land in would be (see pic) and if either at the crossmember vs further back towards the rear leaf spring perch has any benefit chassis wise?

Also, if there any major disadvantage to using bent trunk bars for passenger headspace vs straight bars? I don’t NEED the bends, probably won’t ever have passengers in the back but I like the look of the more hidden bent bars and it would be easy enough to throw a bend in them. I know straight bars are usually stronger but not sure if it makes enough difference to matter.

Thanks!
