[FC] Lower FC A-arms

[Shawn]

Hello all, I don't say much on this list but I'm hoping I can get some help 
with the lower control arms on my Rampside. Mine need replacing and I'm 
wondering if they are interchangeable with another car or truck. I can't 
seem to find them locally but was told they look like Corvette lower arms. 
Is there any other car lower A-arm that would fit an FC?
Thanks for your help
