3 LINK REAR SETUP

I'm definitely going with round tubing. I've got Johnny joints left and right thread so adjustment will be easier.
I completely agree with mounting to the sheet metal, not a good idea at all. I've read about offsetting the top link to the axle or side of the pumpkin.
Art Morrison stuff mounts inside the cabin, it has to and I don't mind doing that. I'd prefer to go 3 link for articulation and adjustability over a 4 link and will use the old panhard bar method. Mainly street driven but for the future I'd like to have a good system already installed. Not sure if I'm using a back seat so...
What length lowers have you got in yours?
