Hatz Biplane Association

I ended making up a post with a plastic saddle on top to fit against the lugs on the fuselage:

The jack is left over from my Fiat Spider days, the plastic saddle is a chunk of HDPE cut to a 16° angle to match the angle of the lug plates:

It's notched about 3/16" deep so it won't slide off:

My Starduster was like that. My Hatz is different:

I didn’t build our plane, so I’m not sure how unique our gear are. There is enough room to place a jack on our gear for tire removal (see attached pic). Maybe yours is similar?

I'm trying to determine the best way to jack up my plane for tire changing or whatever. On the other planes I've owned, there was always enough of a flat surface somewhere on the landing gear leg to put a jack. On my Hatz, though, the plates the spring strut fits between are angled on the bottom so there's no place for a jack to sit, and the brake caliper is also in the way. How have others dealt with it?
