If #4 doesn't work, be aware that 4130 does come in sizes that will 'telescope/nest' properly; the passenger stick in RV-Xs? works that way (The pilot stick is *not* a size that will nest). Buy a foot of two sizes that will fit that are close to your stick size, and butt-weld one on the stick and the other on the passenger stick. If you need the sizes, I'll try to remember to measure tomorrow. Email me direct if you need them.
