Thanks Scippy
I measured mine today while I was working and mine are 57 43 and 47 from the entrance bulkhead forward with 4 total also. I wonder what the purpose of that little compartment was? Probably never know

To me (and it's just a guess) the 16" that forms the little compartment is a result of custom fitting the fuel tanks snuggly, thus the leftover forms a little compartment..........anybody buying that???
