Gear Pattern Opinions Please

It was actually about 180 miles. I picked up my wife at the Philly airport. I live at the Jersey shore. Anyone familiar will know what that means. It means I got caught in traffic going to Philly. Even though it's Monday, apparently it was a holiday weekend (Juneteenth), and everybody was going home TODAY instead of yesterday! UGH. So about half was reeeeally slow going, and the other half was idiots mixed in the 60-65 mph "race".
Anyway, the gears are fine. I changed the oil when I got back. It was nice and clean.
I have to admit to patting myself on the back. I learned about installing gears from an old friend that I helped do it many times several years ago. I've done it 3 times myself, as he passed away because of a fool who caused an accident that ran him off the road. First was on my 5.0 Mustang that has run 11.40's, dead hooking; second was my 360 Duster with a 9" that I put 4.33's in (Towing it to Atco tomorrow night after building it since 2008, about 160 miles round trip, 4500 lbs. with trailer), and now my '95 F150 8.8. It was hard to tell if the Mustang and Duster were quiet because of the solid and poly bushings involved. But the F150 has stock suspension, and runs very quietly. My confidence is building!
The guys on "Roadkill" say, "just do it and have fun". Having a big budget and a support vehicle makes that easy for them to say. But I admit, I did take their advice, to a degree. But can you imagine being at a major airport (or anywhere to or from) with a rear gear screaming?
If anybody out there is at Atco tomorrow, say hi!
