Do the D3 loadspace dimsensions vary by spec?

Hi, hope someone can help me. Do D3s have varying internal dimensions? I've got some boot liners which I got through a clearance wholesaler. I've sold some by mail-order already. I've been contacted by a customer to say it doesn't fit (it's abou 6-8 inches too narrow). But on contacting other customers I've had a response to say it fits perfectly in their D3.

Any ideas?

5 or 7 seater, commercial?

This doesnt answer your question but Disco2 loadspace floor size varies depending on whether you have the extra seats or rear air con as the compressor sits inside the rear boot trim.
