You're having brakes put on it?...
And now you're going to try and tackle taking the entire dash out and refabricating new gauges bracing?....
That whole wood grain dash facade probably has to come out and take the gauges out of the back of it and make some kind of backing plate back there that will accept the new gauges and bolt it to the back of that dash so it faces through..,
If you're not able to do the brakes yourself I'm losing confidence that you're going to be able to take the complete dash apart and fabricate backing plates and make it all work and put it all back together....
