power steering in a HR even though it is a thing is a bit of a waste as they have a worm and shaft setup which is pretty light - easy to adjust too haha), hell i had a lowered front end, low profile 235's on the front, with a little SAAS steering wheel and had no trouble with steering at all, unlike rack and pinion which is heavy as hell without power assist. I also think it wasn't progressive so could get people into trouble at speed. With the stocko tyres (175's) the steering is seriously light.
a/c is definitely doable i have an ac unit banging around somewhere it fits under the dash, but i never installed it.
My HD had the red Premier interior - seriously nice with the fan and demister and stuff but my HR was only Special spec so i missed out on the fan, lol. What a thing to say - has no fan, can you imagine that today - yeah see this lever? it opens a flap under the dash and you kinda get a breeze, but if you get the top end model that flap can also have a fan to blow air.... onto your feet. Oh and it has a heater too, but the Special and base model - no fan or heat.
People really are spoiled now, "no carplay" is a deal breaker.
