I installed a B&M Trans gauge & Vac gauge in the radio delete pocket,worked out perfect.I believe it give a clean look to the interior.
The gauges are always easy to see day or night & I can still use the pocket for the stereo controller.Still wanted a Tach seeing as my '89 didn't come with one so I placed a Sun Pro Mini on the steering wheel,again perfect size & fit.Didn't block the MPH #'s at all & not to flashy/big can staring back at you all the time.....
Simple to do & highly recommended mod.
