I was watching a video & reading text  on John Mummerts New shorter front cover .[ WOW!  What great results with that 331"  Y]     Text reads 7/8" shorter..but uses a SBC damper..  Would this be usable with a Mummert steel Y block damper shortened 7/8" ??  or is the seal setup different??   Im very interested as Im in process  of a 471 blower in my 32 and space is at a premium.  Ive made my drive coupler off his Y block vibration  damper..  THANKS!!   Steve McD
