I am trying to source some rear springs, other than the usual ones....a tad taller and heavier....

one category is the end type.
Ive got tangential, which I guess is where it ends in mid coil so to speak at an angle....
Then theres square, where I guess it would sit flat on a table....
Then theres pigtail, which tapers on the end.....
.
Most on the list seem to be one end square, one end tangential...

Which is the style of a stock FB springs ends?

I cant really tell without pulling mine out, and I dont want to do that yet.

The RB pictures look like its square on both ends.....

Thanks in advance!
Neil
