So I need to replace the shooter rod and barrel spring for my Bally Strikes and Spares, and I also would like to replace all the red plastic posts. There's about a million red posts listed on Marco Specialities and I don't know exactly how to measure the posts... Also, my shooter rod has the beveled metal handle and would like to replace it with the same style, if that's stock. Strikes and Spares owners, love to pick your brain on this! Thanks!
