I know this is an old topic but I was looking to find the value on a NOS 4spd shifter boot I have with the pistol grip slotted hole,I googled the part #3467770 stamped on the ring & the boot for the 3spds comes up,Brad's NOS 70/74 B/E 3spds picture with the round hole,on Brewers they have an NOS #2996405 B/E 3spd with the round hole,I belive some where along the way the factory double assigned the part numbers or something & that #2996405 is correct for 3spd & #3467700 for 4spd,my boot is also vendor code #53495,anyone have a 3 or 4 spd boot with the part #s stamped in the ring opposite from this,also Im looking for a 3spd boot if anyone has one for a reasonable price.
