i am using my manual, that the link i included, has so you can purchase, there or on ebay. the manual recomend Champion J4J, we recommend J6J, gapped at .030" points, .020" it doesn't give firing order, the plug wires only reach so far. the long one goes on the bottom.

Actually you don't want to choose spark plugs based on 44 year old datum either. Here is a chart that is reliable:
