Just a thought here.. and may be a dumb one... but:
Over on the Tacoma side of this forum, it is *very* popular to change gauge colours. I.e. from orange to white or blue (yuck)
here's a typical nightmarishly long thread: Orange + Red?? Yuck!! (How to change gauge colors)
Just look at the first part.
Whatever. point is, lots of people have had their instrument gauges apart.
I've always wondered... they (as you can see) have the needles off in the first couple of pics in post#1. To my eyes, I can't see if those needle posts have a notch, or are just completely round & it's a friction fit on the needle drivers.
1) wonder if some-one previous to you had the gauge cluster apart to fix something & F'd up putting it back together (as in, the didn't seat the needles at their proper "home" spot)
2) carrying it further, if you are really brave, wonder if you could use that info to just turn your two gauges down by 1/4 by re-seating them 1/4 turn back on their pins...
That would be a bit of work though - although you already had the cluster out... (& I don't know of any similar write up for our HL, since our gauges are already white)
