Dennis,
I've recovered ashtrays before and if I had it to do over again, I would re-dye it instead and not disassemble it. It's not really made to be disassembled and, like so many parts these days, it's rather pricey.
A little masking tape and a brushstroke or two and you're done.
(Plus, when you change your mind and decide to re-do the interior in a year, you can re-dye it again.) [:p]
