That's interesting, yes, the SJ410 from the early 80s I'm sure, extending into Pakistani production perhaps.
My vehicle is a JDM JA11 Jimny, which is from when the kei car regulations changed from 550cc to 660cc in 1990, close to the launch of the North American Samurai in the mid/late 80s.
By that time I'm assuming they had the current setup I have, i.e. front discs, rear drums.
And thank you very much, that would be very helpful. The alternative is to order some Samurai rotors from the US. They'll run me about $170 shipped.
