I've got a 2006 with bend front subframe and passenger lower control arm. Local auto salvage has a 2003 with a good subframe and lower control arm.

I plan on swapping over all the other bits attached like swaybar and steering rack. Just wondering if the actual subframes and/or lower control arms have any differences between early R50 and late R50

 

The best way to check this out is by using RealOEM. You select your model, year and month built to pull up templates of all the parts and the part numbers. You can then check you parts against a different year.

 

The subframe and control arms are the same so you are good.

But don't put the stock control arm bushings back. Go ahead and upgrade to the powerflex so you never have to do it again.
