Thank you for posting in our discussion board. This is a good question.
The difference in price is because the 75-032 Step Down Plunger Drill Bit is custom made for us. We like to use it because it makes the hole closer to the 70-009 Plunger Pin for a better fit. The 75-503 is mass produced and makes a larger hole. Either drill work for the 70-009, however the hole made by the 75-503 will be a larger, and the 70-009 pin will be a little sloppy. That said, it will still work. |

The difference between the two pins is that the 70-008 has a larger head then the 75-009. You should match up the pin head to the one you are replacing in your screen.
The 75-503 drill bit is for the 70-008 pin. The reason we like to use the 75-032 for the 70-009 pin is because it is a smaller hole for the smaller pin head. |
