The fit and do work on a Pantera. But there is a limitation. Our turn single flasher needs resistance/current to work. LEDs have such little draw they prevent the flasher relay from working. I was only able to do 1/2 of all bulbs with LEDs and still have the stock relay work. You can try replacing the relay but requires some understanding of the wiring.
I would suggest doing the rear bulbs only. They need the most light and reliability. APC is a good source and you can order from Summit racing.
