The post may include a first portion having a first diameter, and a second portion having a second diameter larger than the first diameter of the first portion of the post. The spacer may include a first portion having a first internal diameter at a first end of the spacer, and a second portion having a second internal diameter at a second end of the spacer opposite the first end, wherein the second internal diameter is larger than the first internal diameter of the first portion of the spacer.
