Easiest way to get elligible for BonusDrive?

I’m very close to 60 days after purchase. I had signed up for Alliant CU to use it primarily for this purpose but Alliant is not on the list anymore. Are there any quick Memberships and CUs I could join for this?

I signed up for PenFed CU for my eligibility. Have to donate to one of there associated partners and then your good to go to sign up.
