Now Chris, that is interesting.
When I put that part number into my 80 series EPC that part number is not recognised.
Nor is there any diagram showing that bush which is probably why Simon and Julian both thought could not be got seperately.
Same thing when I put into toyoDIY, which looks like your screen shot came from. Listed for the 1HZ and 90 series but not 1HDT.
Thats a great find.
