I have been out of town this past week and had very little time in the garage this weekend, but here is where things are at.  Looked at both Lowes and Harbor Freight for a replacement body saw and ended up with Harbor Freight’s body saw located here.  Also purchased an air belt sander for grinding down welds.

Put the body saw to work and was happy with the performance with cutting out the remaining metal:

Should be well within the range:

Need to remove where the floor is connected to the rockers:

I think I will use an air hammer and grinder to remove where the floor is welded to the rockers.  I wanted a higher quality air hammer, so went to Lowes and purchased a new Ingersoll Rand.  Now to remove the final piece and will be able to get a better idea how the patch panel will fit and where to trim next.  Hopefully, I will get some more garage time in towards the latter part of this week.
