"I still don’t see how the cap can be put in backwards? Is has a notch and The 1 is on the front (facing the rear if the car) and wires start there and follow the sequence"
You are correct that there is a notch for the cap and that the number 1 tower is marked.
However, it takes TWO revolutions of the crankshaft to equal ONE revolution of the distributor shaft. You must rotate the crankshaft to TDC on the COMPRESSION stroke, then install the distributor with the rotor pointing to the number one position (on the cap).
