Answer for the front is no unless you use the TR6 radiator shield which fits the TR4A-TR6. This provides the factory mount for the TR6 bar and can also be used for Addco aftermarket bars, possibly others.
On the rear, all IRS TRs use the same Addco bar. But live axle TR4As use a different setup with the bar mounting forward of the axle.
TRF has a trick adjustable sway bar setup on sale right now.
