Could you do me a favor and answer the following questions?
Are all rack ears similar in how they mount to the instrument?
Could you tell me the dimensions to mark to drill?
What size of angle iron/aluminum?
Could i do it with a drill press?
Suggestion:
Start off with the zip tie solution. This gives you an immediate result and allows you to mull over a preference for proper rack mounting ears. At some point, this will become a strong urge and you will find the drive to follow through - possibly when you realise you want that rack shelf for something else...
Zip ties are cheap enough to cut and toss.
The shelf is going to be their rear support, zip ties or not.
