This combination is used to hold the Garmin Quest bike mount kit ??.
The RAM parts; "RAM-B-202, a RAM-B-201 and a RAM-B-231Z" had been suggested to hold the Garmin Quest bike mount kit as the Garmin instruction leaflet shows four holes from the AMPS hole pattern on the bike bracket.
There's an option and a choice. Its the difference of two hole fixing (use RAM-B-238) or four hole fixing (use RAM-B-202).
If you use the two hole fixing option, then go for a RAM-B-149Z as it contains three parts; RAM-B-238, a RAM-B-201 and a RAM-B-231Z ( Z = zinc U-bolt). However, if you prefer stainless steel U-bolt, order then the mount is RAM-B-149.
