Hail Yeah back under the knife

[Normagain]

It looks to me like someone may have replaced the tank and removed the foam in there adding that front bulkhead and maybe removing some key foam. The tank looks like it broke loose, maybe whatever they put underneath it was not tied in well and stable and the tank was not bolted well. Here is a picture of my 74 SF. There was a block of foam in both the front and rear of the coffin and those were both on the top of that bottom tank board, no wood bulkheads at all. The front foam block starts further forward of where your bulkhead is, you can barely see it in this picture.
