Adjusting gear lever bias.....

Hi guys, I'm up to adjust the gear lever bias plate and springs on my Disco Td5 (MY 2000), it became naughty .......there are three bits I can't find the codes to order > gear lever housing rubber boot, cover plate seal and the pop rivets(I suppose these'll be destroyed)(already found springs, bush gear change pivot and plate)......I want to put everything new if I intrude there....

Help me with the codes if you can please.

I dont think the rubber boot will need replacing, I sealed the cover back on with instant gasket, and I put self tappers back in the holes, youll have to drill the rivets out

Good ideas, ......Thanks
