The RAM-B-347U base consists of a 1" diameter rubber ball connected at right angles to a 2" x 1.7" square base. The base has four pre-drilled holes at each corner, making the universal 1.5 x 1.188 (hole spacing) AMPS hole pattern.
We've gone "ala carte" with most of our RAM pieces, build your mount however you want it! Please let me (firstname.lastname@example.org) know if there's something you'd like that isn't listed, or if you have questions about how to build your personal mount.
