Bed panel questions

[vipergtrdj]

I am in the process of restoring this truck I just bought, and I am onto the bed. I have found that LMC has the outter bed panels - but I am having a hard time locating the inner bed panels (Im assuming thats the name). Its the panel on the backside of the outter bed panels.

Anyone have any suggestions before I head to a local metal shop and just get some flat sheet metal to replace it with ?

Year and model would help?

Im sorry, its a 94 Chevy K1500 fleetside shortbed. Any suggestions or help would be great, looking to be pointed in the right direction. I have searched but still not finding anything.
