you can drop the distributor in anywere it will seat on the oilpump drive and get it to work but the correct distributor placement will have the rotor pointing at the #1 cylinder itself in the block (first forward cylinder on drivers side) and the timing mark at TDC on the #1 cylinders compresion stoke, pull the plug on the #1 cylinder , place your thumb over the hole and rotate the engine with a breaker bar, whebn you feel compression start to build up your on the compression stroke, continue to rotate the engine to TDC, once your at TDC on the damper/timing tab , pull the cap on the distributor, it should be pointing almost at the #1 cylinder itself, if not you can loosen the distributor and remove it , turn the oil pump drive shaft with a large screw driver and test fit the distributor back in untill it is, once the distributor rotor points at the #1 cylinder on the block and the timing marks align the distributor may be partly tightened down untill final adjustment with a timing light allows you to set it correctly, 38 degrees total advance at about 3000rpm or about 6-8 degress initial advance at idle will get you started
