Quadralink vs Morrison tri 4 bar

[colorado80439]

68 Camaro ready to throw down on a rear suspension. Narrowed down to one of the 2, looking for some real world opinions, since I wont have the opportunity to drive before I buy.
It's not going to see much track time, so I want quiet and dependable. I tend to over build and like bullet proof reliable equipment. Looking at a floater axle. The rest of the car is DSE front subframe, LS7 NA 630 hp, tremec 6.
Love the look of the 12 bolt but not thrilled about cutting up the trunk.
Thanks Dave
