Thanks the input guys. I have cut out the bad stuff & got it cleaned up and it now looks managable. Surprizingly the rest of the rockers looks very solid inside. I'll be treating what surface rust I can before using eastwood internal frame coat. Used it in the rear uprights and I really like it.
Ufo- I've followed your restoration and saw those pics but I missed the small openings you made. Great idea! I willl copy that. 🙂
