The original design only had one street side skid plate. Not sure if I should add a curb side skid plate as well.
Also I think I will use a Z cut graft to join the new with the old C channel and the use 13" x 1/4" thick fish plates on either side. Not sure if i should bolt the plates together with 1/2" bolts or just weld. I see both approaches used. Any ideas on this would be appreciated.
If your new "C" channel is only 10 guage then I would use 3/16 plates on both sides. Butt weld the joint, grind the welds smooth, and then put the plates over them. I would MIG weld it to reduce warping.
For those who have actually removed the frame from the trailer, it appears that it is actually easier to make a new frame than chase the problem all over the existing frame with reinforcements everywhere. It is an unfortunate situation.
