No, that was many years ago.
Just measure the frame width at the front pegs. Then measure up from the pegs to about the middle of the cross brace. That’s the greatest height you can use. When you search eBay, I’ve found most sellers were very willing to give me those two numbers, I guess cuz nobody buys used highway bars.
Edit: if it’s an inch or two too wide, you can use a ratchet strap to pull them closer. However, just be aware that makes it taller. I did that and almost got one too tall. Also, you will put them behind your pedestal mounts. Which means you’ll need to shim the back bolts to keep it equidistant from the frame, and thus square. I used washers on one, the other I had some metal I cut to size.
