....and after considerable trimming
Yes I know the shock is upside down. The adjustable perch is slightly larger than the fixed one and I assumed closer to the OD of the spring.
Again, YMMV on the trimming required. This is just what had to happen to get it to fit up nicely on MY particular subframe. It isn't hard. Just time consuming. You grind a little, then test. Rinse and repeat until you get a nice fit then tack the sucker in place.
