Yep, still stocked around here in most stores. And it's not the leather type either, but the less expensive vinyl or whatever it's made of. Leather look-alike.
Very inexpensive and not really all that hard to install. Just takes a bit of time on your part. Probably best to give yourself a 2-hour window if you decide to do one.
By the way though, the real leather ones are just "better" in my opinion. They don't gum up as quickly with hand oils and dirt in hot climates, clean up better I think, and are ultimately more durable. I have used both types on my daily driver cars and trucks and Broncos and the vinyl ones were nice, but deteriorated within a few years. I have a couple of leather ones though that are over 20 years old and counting.
And even at double the price, they're still pretty cheap upgrades to your ride.
You will also have to do it to your existing steering wheel, or find a half-year-only original. You can't use the earlier style '66 to '73/early-'74 style because the horn contacts are not compatible with those on the column.
The only solution to getting that style wheel is to find the ultra-rare mid-'74 version that had the old style look, but the new style horn contact orientation.
I have not seen one reproduced yet, but it's possible the big importers/manufacturers (Scott Drake, Dennis Carpenter, LMC) have one and I just have not seen it yet.
Good luck.
