Mike: Call Califonia car covers, They will send you a sketch to fill in the blanks for dimensions of your car. I have both the full cover with (2) roll bars, cannot be happier, my little baby sleeps well under her cover. The cover even has stretch areas by the wheels to fit snug as a "bug".
The cockpit cover like Roscoe's is also a good idea for the interior area, I asked for (2) additional straps and they sent them to me to attach to the Miata cover, bye the way there was no year specified for the Miata cover. I carry that with me on threatening days and "hot" days to protect the interior.
California Covers - no regrets, great company.
