I'm pretty sure the height should be 1.25" not 2.75" ??
I'm not 100%, but I believe the 070 clutch - or one similar dimensionally - was used with all 26" radiator applications (not sure about A/C cars) where a Hemi, A12 Pkg, 4-speed 440, or 383 Axle Package was installed. And the height measurement was 1.25"...Someone else may want to chime in on this?
