e30 and e46 (e36, e30) m3 caliper lug spacing??

[SA E30]

Hey guys.

I'm having a hard time locating what the brake lug spacing on the standard e30 strut is, as well as what it is on the e46 M3 (which is the same as the e36 m3, and e30 m3).

Could really do with the spacing as I don't have the parts off hand to measure.

Thanks!
