I have 99 Miata with 5 speed. It came with 4.3 rear diff originally... I have since swapped the rear for a 3.909 torsen (kept the 5 speed tranny). Speedometer is way off.

According to the finishline performance site, there's 2 different part numbers for 6 speed cars (all 6 speeds came with 3.909 rears right?). M528-17-400A and M534-17-400 with them listed for 99-00/03-05 and 01-03, respectively. Reference Page

No idea what the color of the gears are that I need....if you know what color or exact part number I'll need I'll take that info too!

Thanks

IIRC, the mazdaspeeds were 4.10s

Someone fix me if I'm mistaken.

Rear end came off a 2001 SE with 6 speed, so that's probably the safest route anyways... M534

edit:

according to this... 04-05 was in fact 4.10, but the rest were 3.9. I dont know why finish line is putting the 99-00 6 speeds in with them..typo perhaps.

I have a 99 speed sensor that is doing me no good. Interested? If so I'll check the color in the morning.

Yeah I'll take it it's from a 6 speed car (for 3.909 rear diff). If you're not sure maybe we can use the color to confirm or deny

I definitely pulled it out of the 6 speed I bought.
