Measurement for Rack Ears for TI Desktop 1

Hi,

as everybody knows its almost impossible to get Rackears for the TI Desktop 1.
So it occured to me, that a friend of mine (a locksmith) could make them for me.

Problem is, i need the exact measurement of the rack ears and really dont know how to get hold of it.

I'll try to get it via support but not sure if they hand them out..

i'd be grateful if anybody could help me out with the measurement!

Thanks in advance!

As expected the support can't or wont send me the measurement.

It'd be much appreciated if anyone could help me with this!
