Whats the correct angle to triangulate your upper bars?

Im just wondering what is the correct angle to put my upper bars on my 4 link so that the rear end doesnt hop around side to side?

40 is usually the standard i think.

Alright thanks. I heard 40 or more but wasnt sure.

Alright, after going to look at it there is no way i am going to be able to mount the bars at 40 degrees, my frame rails in the rear are only 31 inches apart and to be able to run 40 degrees i will have to have bars that are 1 ft long. Are there any other solutions? besides like a panhard bar? Is it that big a of problem for most of you?

its 60

i hear 45 degrees, but ive never setup one at that angle before, because you cant fit a 4 link inside a frame and have it any decent length. most of mine are 24-30 degrees, this one right here is barely 40 degrees:

those bags don't look too sturdy.. may want to gusset

should need a bolt in gusset......

how are you guys measuring the angle that the bars are at?
