What SWAY BAR to choose

I emailed them and that is what they suggested. I'll check again before I order.

Didn't we have a member at onetime that was a Hellwig employee?
stock 73~76 bar measures 37" eye to eye (center)
73~76 setup measures 43~44(ish)" shock to shock

remember to take into account the strut bars when deviating from stock or a known entity on bar width and pick up point to the tab. having the end links canted out at an extreme angle isn't great, either.
