Here is some free white speedo and rev counter faces for your games, i made them in photoshop and you can use them royalty free i dont mind if you use them for commercial projects.

Locate your 3dRad folder/3dRadRes/objects/sprite/data/ then add them into that folder once they are in there close it and start 3dRad and add a sprite in your games to find them or change the default speedo background sprite/picture.
