Getting to the tail lights of an 89 corvette

I have a 1989 Coupe and I removed the fuel door and the fuel boot and reached in through the access. You have to have skinny arms, though. It's a tight fit. I've read where some remove the inner fender, possibly the spare tire too or remove the rear fascia. Never tried those since I have skinny arms and can reach through after removing fuel door and boot.
