ok im having issues reassembling bed.... i bought this one already disassembled. so i will have many issues with reassembly. i have the assembly manual but does not show cross sill location... i have 3 cross sill 2 are the same size ( havent measured just eyeballed them) the other is a different looking one completely and i dont know if it goes in front or bad and really dont know what goes where as far as if blocks are needed and bolts needed as well. thank you for your time and i hope i can solve this problem quickly.
