How important are torque box braces on my 88 vert 5 speed? I have 4.10 gears, welded frame connectors with Stifflers web bracing, Strange adj. Shocks and struts, upper and lower control arms with poly bushings, and lots of bolt ons. Not big hp, I'm guessing maybe 270-280 hp at flywheel. Tires are 285/40/17 BF Goodrich regular tires NOT drag radials and they spin pretty easy. I think It's time for drag radials. I also plan on a 4 point roll bar and figure doing the torque boxes at the same time makes sense. Any ideas on labor costs for each mod? Thanks.
