WANTED: 4 BIKE PLATFORM BIKE RACK IN SOUTH AFRICA

Good day, I am looking for a 4 bike platform bike rack. Unfortunately it must be a platform bike rack where the bike stabilizers are between the bikes, and not where the bike stabilizer are on the towball end of the rack with stabilizer arms. The reason for this is that I have a car with an unfortunately placed case-enclosed spare tyre on the back door, and found that the bike racks with stabilizers between the bikes work best for my situation. Please see picture for an example. Any help would be much appreciated. Kind regards.
