81-91 Dash Insert Source

[thefraze_1020]

So I've been shopping around on the parts sites for the passenger side black dash insert without A/C.

I'm seeing what appears to be the same part for $59.95 at LMC, $109.95 at Classic Parts, and $69.99 at Brothers.

Is there a difference between these parts that I don't know about? What's your guys' experiences?
