Part number and/or where to buy coil spring bumpers/spacers? And spring compressor?

[tdoublenastywitit]

Hey so im converting my 300td to non sls springs and shocks. Ive never replaced springs or shocks on any w123 before. Ive read there are these little rubber spacers/bumpers/cushions on the top of springs where it meets the body. Ive also heard there are 4 different sizes.

I image I might be able to get away with re using the original ones that are currently on there but I would like to replace them. Does anybody know what these are officially called or the part number and/or what size is best. I would prefer ride height to be on the higher side of things but not super high. (This is for rear springs only)

Im converting to these w140 springs

And does anybody have the link to cheapo ebay mercedes spring compressor that works.

Thanks
