^^ Yeah you could buy an entire car for what the dealer would want. That being said I have bought other parts from the mazda dealer that were actually cheaper compared to buying U.S. mazda dealer parts.
The tension cables I believe are the same for NA and NB as are the tops. Only real difference are the windows as 1st generation came with plastic zip out rear window as opposed to safety glass. My first generation has a black cloth top and glass rear window,obviously replaced by the previous owner.
Have fun.
For some reason the cables seemed to be different parts for NA vs NB, dunno
I got the cables and started prepping for installation, that's when I figured out I don't have the "Installation kit", bits of velcro, pop-rivets and bow-end caps. I think I can improvise, might call Moss Miata and see about the end caps. One other thing, which I'm often running into lately is trying to find certain things in Canada that are not available, probably for banned ingredients or somthing. Anyhow, Robbins says to use 3M 08011 weatherstrip adhesive, which doesn't seem to be available in Canada, but 80119 is, so I have to find out if it's the same stuff.
Ran into the same thing for a Wurth Eurogel sealant and some Valvoline grease, can't seem to find it in Canada.
