Hi, I have question about my 70 Challenger R/T missing the master cylinder.

I think the car was originally manual brakes. Has drums all around. Car came with a new manual master but no pushrod or hardware to the pedal. What am I looking for? Not 100% sure what to buy.
also, I’m missing the fuel tank, I ordered everything up that I need for that, but I’m wondering if anyone has pictures of the bottom of the trunk pan before and after tank installation?
thanks for any informatio.
