3-Link rear suspension torque are questions

[Stg1Regal]

Done some looking into a 3-link torquearm suspension,like what I see, but I had a couple of questions.



If my car, a G-body ( 82 Regal),dosn't have a kit out on the market for this set up, how does one determine the correct torque arm length?



And for that matter, where to mount the front pivot point.



I know a Watts link will be needed and seen the one from Marcus at SC&C and will likely go that route.



The reason for my asking is... seen over at the BMR website the big plate mounted to the rear of the diff,then covered with a Diff cover, and all the torque arm mount points were incorporated into that, wonder if possible that idea and design one myself, or found one of DENNIS KIRBANS replicated GNX diff covers and design a torque arm off it.



Any way shape or form a decent front mount is required, all the ones I seen, seem to mount near or around the trans out put area or even on the trans crossmember itself.



I have one of the CROSSMEMBERS.COM dual hump cross members, maybe thats a good spot.



Are there any good suspension websites to go too, to determine the length and geometry of the 3-link?



Again thanks ahead of time

Not sure if you are interested or not but you can purchase any component from our torque arm kits if you are interested. In fact, the very first kit sold went to a custom builder who is adapting it to a Studebaker! If you want to adapt or convert the 10 bolt to something other than the OE 4 link, our differential mounting plate would provide a good starting point to build from and already incorporates a Watts link (you would just have to fabricate the frame mounts for the Watts links). I am not completely sure about this but the torque arm may be pretty close to the correct length to attach to your current crossmember and may just simply require two tabs welded to the crossmember. A few simple measurements would determine the compatability.
