1950 Ford Custom - inner fender replacement

[spikestik]

I am working on a 1950 Ford Custom restoration and have hit a stumbling block. The inner fender aprons are available as NOS through Dennis Carpenter but for only the passenger side and even then they are not complete.

There has to be something I can use in place of the aprons on both sides....I just cant find what it is.

Thoughts and advice would be appreciated for this new Ford Barn user.

Thank you
