New spring install?

Ok here you go:

the superstock MP springs.

002 = right is 51 1/2 roughly from hole to hole
003 = left is 52 1/2 roughly from hole to hole

(within 1/4 inch error)

Yes, there is a left and right handed spring. If they are MP springs the right hand part number is even and the left hand part number is odd.

That one does look like it is a little far forward. The springs will "lengthen (get longer)" when you put weight on them and may end up sitting correctly. Finish putting it together and drop it down on its wheels and see how it sits.
