Correct. That's just as well; the '69s had a throttle plate anti-ice system that requires a special exhaust manifold and makes the carb boil like a teakettle. The system is also unnecessary with today's gasolines. If you still had the '69 carb, you'd wind up doing extra work to bypass this system. This what you have is not near the top of my list of favourite Slant-6 carburetors, but you do have it, and if it's in basically sound condition and you're not planning on upgrades (2bbl, etc), then it's a fine starting point.
Do you have a 170 or 225 engine? Automatic or manual transmission?
Are you trying to do a 100-point back-to-factory restoration, or is driveability/function at the top of your list?
