I was reading through the books I have last night and at breakfast this morning and found something odd. Where are there supposed to be brass bushings? Is it the pivot point (i.e., the end away from the shackle)? The shackle end? Both? Neither? The pictures in the parts list book shows the front spring's bushing being on the shackle end, but the rear spring's bushing being on the pivot end. To make things more confusing, the detailed parts lists below the pictures have three variations (normal, and two heavy duty versions, one for early 2As and one for late 2As and 3As) and for each of the front and rear, only one of the three lists the bushings. In the General Spring page given in the post above, the front springs (8 and 10 leaf versions) are described as "front eye bushing included", while the rear springs (9 and 10 leaf versions) are listed as "bushings included". Walcks seems to say that the bushings go on the pivot end of both front and rear.
Some details from the books are given below. I think these agree with each other fairly well, if (for some reason) the specs in the Service Manual for the front are for the heavy duty option.
But I still don't have any thing official for arch. A post above lists 2-7/8" for the front, but if I read correctly, that was from a used spring, and may have some sag.
It also seems that the rears should have two leaves wrapping around the eyes, but only the heavy duty version of the front should.
