[DeTomaso] Chassis

[Joseph F. Byrd, Jr.]

Is there an spherical ball design that can be installed into the existing A-Arms?   Is there an illustration of how it stacks?

I have look into spec'ing components for such a design (attached)

Dear Stephen and Joe and John,


              I believe the best option is to install the Sphere Ball/Bar sway bar mounts available from  Pantera Performance Center, Pantera Parts Connection and other vendors.  It seems to be the best upgrade to slightly imperfect 1970-era engineering.


                      Warmest regards, Chuck Engles
