Mini brake rotor vintage? (1 Viewer)

[jim45r]

I have a pair of mini knuckles of unknown vintage that I got from a buddy for my front disc conversion on my FJ. I took the old rotors off to clean the hubs & knuckles, and like a DS, I tossed them in the scrap bin before I checked on replacements. Now I read on All Pro Offroad that there are early ('79-'81) and late ('82-85) vented rotors, not interchangeable according to them. There are 6 hole and 8 hole versions. It says to compare, and yep, dur, my scrap bin is empty now. Dang that spring cleaning!

Is there a way I can tell the year from the hub or knuckle? I had to pound the studs out to get the rotor off too, is that a clue? Parts America online shows a picture of an 8 holer for an '81 cruiser.
Any Idears? Will the old style knuckle/hubs fit a vented rotor and my V6 calipers?
Thanks.

My 85 (last of the solid axle) has solid rotors, absolutely the same as my uncles 83 mini. If you want vented rotors, you'll need the 86+ calipers and the LC rotors IIRC.

Yep, I already have '92 4-runner calipers and I'm concerned about whether there is a difference between the early and late hubs as far as mounting the vented rotors goes.

look at your hubs. the 6 hoe will hold the rotor on by means of the studs. The 8 hole will hold the rotor on by means of the studs and two bolts

That's the trick! I've got 8's.
I guess I should have been able to figure that out myself if I'd dug them out of the box and looked instead of jumping to conclusions. I've just had a bad string of throwing stuff away that I end up by needing . . . maybe my luck is changing!
Thanks for the help!
