Looks like your on the right track, I raised the tail by putting a floor jack under the tailwheel. It's not to bad of a job, helps to have an extra set of hands for the bottom ones. With a little blood and sweat I was able to replace all of them with out removing anything from the engine. I don't have any good tips you just have to do what it takes to replace them. I did replace the bottom ones first, by backing the nuts off on the top ones as much as possible to allow engine movement.

Never heard of Curtiss safety issues. I've got em' on the Cub, Stearman, and super Decathlon. I've had the wing drains leak on the Stearman periodically. Anyone got a picture of what the Safe-Air alternative looks like?

I'd probably be most concerned with the gascolator/low point drains leaking and not knowing about it. The Cub has a Steve's Gascolator with a Curtiss on it.

Look on the Aircraft Spruce web site for part number 05-01865 (Saf-Air CAV-110). I replaced my gascolator's Curtis CCA-1550 with a CAV-110. The T-head on the Curtis was difficult to sump because of the odd angle on the gascolator and the opening in the enginecowling.
