Hi and welcome!
Bear in mind that the old "dog bone" resistors were MUCH larger than modern equivalents. 3 watts is adequate. Don't go any lower in wattage! If it makes you feel better, use a 5 watt replacement.
The original alignment tool was made of Bakelite. Replacement alignment tools made of plastic were sold by Antique Electronic Supply once upon a time, but they quit selling them about the time they switched owners and shifted their focus to the guitar crowd.
Some folks have made their own from thick, stiff (not flexible) plastic tubing, somewhat larger than 1/4 inch. The body of an old ball point pen is ideal for the job. Heat a 1/4 inch hexagonal piece of metal such as an Allen wrench, when hot insert into the plastic tube. Let cool and separate. Voila, instant Philco alignment tool.
