Drill Guide for Proline caps & Arrma 3s/4s posts

This is a drill guide to use the stock body posts on Arrma 3s/4s cars. Slip the guide over your existing body post, and use a 9/64" drill bit to make a pilot hole for the Proline studs or buy 4x16mm Socket Set Screws, Cup Point and maybe some M4x6x6 Thread Heat Set Insert and make your own. Either way, your choice.
