It's hard to make out in the photos but you need to open up the sill on the four door rocker or swap in a two door version. I have seen people weld right to the sill but if you do that the water has nowhere to go and you'll eventually have problems. [/quote]

You're right. In my case we'd studied the remains of the 2dr parts car and reworked the 4 door rocker to provide for drainage in roughly the same manner.
