I really appreciate the guidance here. Just found some rust within the rear crossmember & within the battery box. The chassis other than what's on the crossmember looks good. As for the battery box, now has a hole just under the battery from me cleaning it out. Rest of the box looks fine. Yeeesss I changed the direction of the battery so it will not drop through. So far from what I can see the bulkhead should be fine. Under the mats no rust present and the seams on the floorboard appear to be good. I will check the other areas you guys listed. Thanks again for the help!!!
