I'm in here because I simply got flamed by the pretentious lot over in the Land Rover forum. Since radius arms are also a mainstay on Ford products I was hoping that someone here could provide real information. I intend to build custom links for the front and rear of my IIA hybird (D90 chassis). What are you using for the threaded portion on the link (assuming that you're not going with heim joints or other bushings at the frame). Is there a supplier of such pieces, are they being machined out of rod stock or is it a big ass bolt cutoff at the head (I'm joking)? I'm on my way to building a three link similiar to SG's but I'm using Currie 9" HP's and will be fabricating the bracketry. This will be a daily driver and not used for EXTREME 4-wheeling.

I think I know what you may be asking for. Try polyperformance, he sells some stout all-thread. Here is a quick link to it, check and see if that is what you are looking for.
