I am planning to do the very same procedure on my 300TE: exchanging all links, rubber parts, subframe- and differential mounts.
Do you remember the source of that kit? I think 250$ would be considerably chaper than buying parts individually. By the way, would you recommend changing the accumulators at the same time for convenience (do they age at all?).
Your and other people's input is very much appreciated.
