Can you put spacers on top of Specialized adjustable stem? I know that the stem is offset by the angled shims and has an angled top cap, was wondering if there is an angled spacer as well.

I'm curious because I just came across a picture of spacers above a Specialized adjustable stem on ebay - http://cgi.ebay.com/Specialized-Tarm...ht_1921wt_1139
