Default Axle leaf spring mount hole spacing

Is there a standard mount hole distance between the 2 holes that leaf springs use where they attach to the axle? Or does it differ between manufacturers? I'm making some leaf mounting brackets for the T-Rex 60 axles since they only ship with damper/coil mounts, and I want to make sure I use the standard spacing, if there is one.

Or, can someone at least give me the hole to hole spacing of the SCX10 axle leaf mount? Are they M3 size holes?

Yep 3mm holes and rc4wd and tamiya use the same spacing between the holes..

Shall see if I can dig up one of my old Hi lift axles to measure...

I just got some Tamiya High-Lift leaf springs and HOLY CRAP they are stiff. Its unreal. I think they are going to be totally unusable for the suspension response I'm after, even on a heavy vehicle. I'll try my hand at home-mode springs again, and if all else fails Ill just get super soft RC4WD springs.

Hole info is (taken from a response on rccrawler):
The end holes are .114 in diameter, the center hole is .105 The outer hole spacing is .476. The middle hole is centered between the 2 outer holes. 0.114 = 2.895 mm. 0.105 = 2.66 mm. 0.476 spacing = 12.090 mm.

Another source of leaf springs is Cross. The ones they have on their HC4 are firmer than the RC4WD ones, but not nearly as firm as the Tamiya ones (I've used both on different trucks).
I just finished building a Cross HC4; it's a heavy truck too, and I really like the leaf's it came with. A single metal leaf and the balance plastic, they work really well. With the right shocks to slow the rebound down, they look really scale
