Best way to order from them is to call Steve at Tousley Ford...he is the MAN when it comes to getting stuff. I ordered my shift knob from him, got it in less than 24 hours after placing the order.
I'd go out the top with both. Subframe nuts breaking loose and spinning is no fun. I go out the top on almost everything now... unless it is a southern car.
more electronics to take loose, but the subframe is a pita
the steering rack shaft is hard to clear the hole in the firewall, the subframe is heavy as balls, the frame nuts spin in their locators if you try to pull the subframe up with the bolts, ect ect
