How important is it to orientate the coil springs in the same position that Toyota did? Here is what I am trying to do. I have a 1999 4wd 4Runner with 215,000 miles that I bought used with 140,000 miles on it. When I bought it I did tires and alignment. Now with an additional 75,000 miles its time for tires again so I decided to also do quick struts, rear springs and shocks. I found that the front passenger side had the original setup while the driver's side had the original spring with aftermarket shock. The paint marks on the driver's side faced to the inside or engine. This is different than what was original. The new quick struts don't have paint marks but are marked left and right but the position of the lower spring perch or end of the coil is not in the same position as the original. Does this make any difference?

Also, Toyota calls out 2 different part numbers for the spring. What is the difference? I see no difference between the 2 quick strut springs. The only difference I see is the orientation of the 3 top bolts to make it left or right. The new coils have the same number of turns but the material is of a larger diameter and about a 1/2" longer.

So, do I need to be concerned about the orientation of the end of the coil spring or just put them in the only way they will fit which is different than Toyota's.

Thanks in advance for any help or insight.
