Shackle q's (in the right area of the forum)

I keep hearing reference to an ideal shackle angle, but in all the pics that are posted, they say something like "not quite the ideal shackle angle".
I searched and came across some toyota treads that said 30-45* back is a good angle. Does this hold true for my fullsize ford truck as well as the little toyotas?
Also, is there any way to calculate what is the best shackle length. Since that depends on the spring length and arch, am I correct in my thinking here, or is it pretty much as long as the shackle can swing it will work?

I run all of my shackles at 32* kicked back.

Flex seems good, so no complaints.

Shackle length can create rather dicey conditions in stability the longer they get, as well as changing the angle on your pinion. So, there really is no "right" or "wrong" way to determine what will work best for you. Other than research, trial and error.

Do a search on the board, if you see someone running 12 inch long shackles, I wouldn't recommend copying that idea.
