Post your Dash Pics
My 69 doesn’t have a lower pad, not sure if it’s in the way, and mine has a few more screws, like one by the glove box end, makes me wonder if you’ve got one behind it. After that what will give you the most wiggle room is to disconnect the (battery first) speedometer cable. The little bulb sockets are cheap on eBay. The edges of the bezel are sharp and will scratch paint so protect your column and dash. A few of the bottom ones are easier from underneath.
