68 Barracuda dash panel help

Dad n I changed bulbs in his 67 cuda to LED while his inst bezel was out. Some worked, some didnt. Not impressed. When the car gets touched again, I think bulbs will be put back where "warning" bulbs go...oil, brake, high beam etc. LEDS only for illumination on the inst faces. Then I will chk for proper operation on LEDs and bulbs.
