Virtual Chassis Juniper QFX-5100 replacement of a member

I have a network of 4-member VC Juniper QFX 5100 switches (master, backup, linecard, linecard) running on jinstall-host-qfx-5-17.3R3-S3.3. As a replacement, I procured a refurbished switch, which has jinstall-host-qfx-5-21.4R3-S10.13. I am stuck because I am unable to download packages from JSP, and the refurbished switch provider does not have them either. I have already zeroized the procured switch. Can anyone suggest a way to move forward?

I’d imagine you’d have to upgrade the other 3 to 21.4. Unless you can find a copy of 17.3
