rear sliding window .which part do i need ?

Hey i just need a little help here . i bought some window locks but they didnt have the little bushes that go between the glass and the window lock on the inside . but the microcat shows two part numbers for 15 and 29 MUC1705 & CNT000010 . they are for a 300tdi defender . i have to order the parts and ship them to me so i want the right ones

well ive ordered both sets for 10 windows @ £31 shipped to me , but i will find out which is the right one

for those who might need this same part , MUC1705 is the correct part
