Anyone know part number for the newer updated ZF5 shifter boot? Supposed to be a newer PN that is quieter or has more sound dampening in it. 460 truck is fine with stick in hole through floor that mud splashes through and spinning tires on the 3-4 shift but gonna be all eXtra Luxurious on the IDI and have fancy stuff like carpet and quietness, despite my urge to just rhino line the floor and call it a day.
