I'm not a guru, but as a former DL1000 guy, and with Jay's instructions, doesn't sound too hard, especially if it's one of Jay's subframes.
So . . . what kind of subframe is it?
What sidecar is it? Is it that Dnepr you were going to Las Vegas to get?
You say you have all the components--you mean the right length struts?
Got any pics?
