Dash Pad And Heater On 1970 Boss Trib.?

I am going to replace the dash on my 1970 Boss Trib. Does anyone have any thoughts on the best quality Pad? Also, I thought about just doing the heater core part, but maybe, since I am under there ... do the stereo, speakers and ac at the same time?

It was an AC car ...

Any thoughts on:

Pad quality?

Just doing heater part and waiting to buy AC later?

Stereo

Front speak should be now for sure though, right?

Thanks!

which one is the ford replacement -- is that the original ford tooling one? for about $350-400?
