Bob,
I assume that this is the set pictured on ETF:
http://www.earlytelevision.org/delco_car_tv.html
For a CRT, I'd buy one of the inexpensive universal test CRT's and use that until you get the thing working. I suspect that the set used a round glass 7 inch magnetic deflection tube, not the 8AP4 which was a metal bell CRT. The style of mounting bracket is rarely used for metal tubes.
First, I question it being made for a car.
I suspect that it was intended to be used as a field survey monitor and mounted inside the back end of a small panel truck and it could be used in remote areas where there was no AC available.
There appears to be a nameplate on the chassis. What does it say?
You also seem to be missing the complete power supply, which probably would be mounted on a different chassis. Unless you can find more information about the set, you probably will have to reverse engineer the set to build a power supply.
Test CRT's are discussed on:
