well I did my own & all I can say is, I think it isn't that hard - in hindsight.
the instructions are mostly useless. I tried to put in springs upside down / backwards til I took a break and came back with fresh eyes.
Broke a couple of those little tabs that fit into the holes on the metal holder. I cannot believe this is the best way to build these things....
Anyway, the only ones that were really tough were the turn signals - that's where the springs were difficult to get into place. I broke one on each side as I was putting the new ones on. Bought a second set for around 20 bucks & used second ones from that bag.
The horn & high-beam ones were easy, popped right in. Same for start & the kill switch. They just popped in, no biggie.
They give you a little plastic tool for the cruise controls switches. It works just as the instructions describe it should for removal & installation. No biggie there.
I did wind up using the plastic tool to push the turn signals on. There must be a better way....
Anyway, this is doable, don't get frustrated. 50 bucks? Well I would have spent it at the time. But looking back I'm glad I didn't surrender to the paid parts changers!
