Thank you OP and contributors. I received the knob yesterday and installed it in less than half an hour. I did not glue the boot to the boot ring and it still comes out looking OEM. The major point to remember is to cut large enough holes for the tabs, so they will lock in place when you re-install the boot ring. Overall terrific mod.
As reported earlier, the weighted knob does improve the shifting especially between 1 and 2. I did not find the lower height causing a problem with shifts and hitting the idrive.
