Pinion Snubber or not?

Hi,
I´m building a SS/B Barracuda for Nostalgia and Exhibition Racing.
When I start seeking for a Pinion Snubber, I notice quite a few guys recommend not to use this device with SS Springs.
Car is set up like it would have been done back in the sixties. Race Hemi, 4-speed, Dana 60 with 4.88 gears, #002-3 SS Leaf Springs, 25" Imperial Shocks. Up front is 90/10 Shocks, and all this in a 3000lb Fastback. Slicks are 10.5" something...
SS Springs are from the seventies, in case there is some changes in stiffness compared to the newly made, and also have some additional clamps on the front segment.
I old man take this for granted. A Pinion Snubber is adjusted close or tight to the flor pan.
Of cause the Chrysler Guys in charge for the Racing Program had this thing very well worked out, but still, what´s this deal about skipping the snubber...
Need your experienced advice here :)
Thank You, Stefan
