Replacing rockerpanels and floor could use some advice.

Well 1fast340 Even being a body man for 40 years I learn new things all the time.
Your plan sounds good, If I were you I would not over weld on the frame because it is made from a higher strength steel and over heating it will make it week. And you should use a weld through primer on all your overlaps so it won't rust later on it comes in a spray can and not real expensive.
Would love to come to Sweden I bet it's nice there, and your English is just fine.

Thank you Fred for your advice i read it on my phone without logging in and just never got around to answer your post until now.
Have started on this now,made the subframeconnectors and welded them in last weekend and will start on the new rockers tomorow after going to the hardware store again, have put some more thought into this and i think im going to buy some smaller 1"x1" or 3/4"x3/4"square tubing to add as reinforcement to make sure nothing especiealy near the dooropening start moving and to help using as reference to make sure i get everything back right again when i start cutting and welding,im alitle nervous about this.

Hope you find some time to go here,its not the cheapest place to visit but quite nice in the summer and if you do some reseach beforehand you can go see some carshow aswell,there is plenty of very fine american iron over here :)
