KKE has this shock for $159 plus shipping if you would like to pick up a spare and give this a try. It is in stock (Los Angeles area). PSM does NOT have it in stock, but they would probably charge the same.

It is MA40B03
but give them the following info to be certain:
-460mm distance from top to bottom mounting positions (center to center of mounting holes)
-10mm bolts top and bottom (mounting holes)
-22mm wide upper mount bushing
-350lbs/inch spring
-rebound adjustment is at the base of the cylinder on the lower mount
-compression adjustment is on the top of the ballonet
You can take the photos in this thread if they want them (he asked me for pics).
If you have the Templar M, check these measurements against your shock. PSM sez it they are not interchangeable, but they may not really know. You need room for the ballonet which is angled slightly back when mounted.
