TCI powerglide adapter kit

any of you guys have any first hand knowledge of the adaptor kit, which mounts the sbm to a glide? I've been searching high and low, as you know from some of my posts, for a JW Ultrabell to do the conversion.

well, got some bad news today. not only have they been on backorder since december, the JW rep told my vendor that it will be the last of september at the earliest, and most likely later than that! I'm not waiting any longer, because I want to test and get the kinks worked out of the car, before the end of the season. that way, I'm ready when the points races start up in 2014.

so, I looked around at other options tonight, and came across the TCI kit. looks simple enough, was just wondering if anyone has any knowledge on how strong they are, fitment issues, and that kinda thing. thanks in advance for the replies.
