I made a Shift Frame ver.2 and install it temporarily using the existing shift boot.
When I made it, I used the shift frame for Auto tranny.
And cut it.
Also, I cut the acrylic board for the blank area.
Regarding the Alum. ring, I asked the shop to make it.
Cut the frame roundly like a following pic. After that, rasped the surface smooth.
Made screw holes using drill. And sprayed primer over the surface.
And painted the surface mat black.
Installed the ring into frame!
