Im doing an rb30det at the moment and wanted to make a drilling guide to hold it all straight and in the right place.
If you are doing an rb30det and are a little confused on the location of the top tensioner bolt then you can use this to help you out. its an stl and it will 3d print on your printer,
The hole in the middle is 8.5mm which is the perfect taping size for a 10 x 1.5 mm tap
