Parallel or triangulated 4 bar??

. . . my plan is to offset it a inch to the right so hopefully I won't have the opposite when I am braking.

There will be a little asymmetry, but with the UCA at only 1" eccentricity it won't amount to much.

Some sort of arrangement using a plate between the cover and the housing sounds like a better solution than attaching directly to a casting not designed for heavy local loading at that point. Buick specifically used this sort of plate with two attachment points for the traction arm on the GNX and Kirban continued this design as an aftermarket offering at least for a while, but I don't know if it or parts of it are still available. I think the offset was a little more than 1", which might mean a little more asymmetry in a 3-link but still shouldn't be a deal-breaker.

Side benefits: gaining a little diff fluid volume can't hurt in a high powered car, and the more rearward position of the axle side UCA pivot makes it easier to get some length into your UCA without compromising the rear seat.


One further option might be to use an axle out of the current Mustang, as that car already comes with a 3-link suspension and has a properly designed ear for attaching the UCA. Watts link kits already exist for this axle (Fays2 and Steeda that I know of).
