How to mount an aftermarket Tilt column 64-66 truck

[64GMCHorsepower]

I'm looking at getting an Ididit column....

I know the original floor mount will work fine, but how do you go about holding the column at the dash.

When you lay the column in the bracket under the dash, the original columns had 2 bolts that bolted to the support.

I have seen the underdash mounts and just wondered if anyone had used them...

or what other ways do you mount them securely.....

Thanks for the help
