I'm okay with taking partial bits, like I'd have to do on the new Heidt thing, and then adapting it to work for me, but I distrust my ability to properly build a complete cradle that includes all mounting points for the arms and everything.

My impression was that for the LX or Viper rears I'd have to build everything. Am I incorrect in that? Are they sub-assemblied enough that just an adapter need be fabricated?

Edit: Okay, the LX is a subframe, but I can't find a complete picture of one anywhere. Anyone have a link?
