I'd be very interested in your driving impression on the change between the 2 bars. I've actually got the same 1 1/8" Hellwig front bar and also a stock 15/16" OEM front bar to go on my 73 Barracuda which didn't come with any sway bars from the factory. I also have a stock rear sway bar to go on as well, so want to pick the front bar that will work best with 3/4" rear bar.
