I put a 1999 Taco Xtracab 5 speed 4x4 shifter boot and the plastic frame its attached to in my 1988 4runner. This part has 2 cupholders built into the passenger side- one cupholder thingy that slides back and makes room for 2 if needed.

I had to cut a little bit of plastic where it meets the transmission hump with a utility knife, but otherwise it looks like it was always there.

Really nice to have 2 cupholders now.

AFAIK, this part only came on 1998 and later Tacos, and only on the Xtracabs. If you want the boot to fit right it has to be a 4 x4 manual.
