good morning forum friends,

Please give your advice about shock absorbers..
And WHICH brand to go with???
82' 240d
One of my rear shocks began to leak(bad) this week, should I replace both? How long can I drive on it while leaking?

Anyone have any experience with K-Y-B shocks. (they are half the money) are they compareable to Bilstien's?
I saw Fastlane has "KYB Gas-a-just" what are they??

I would really appreciate if someone could comment on what to expect between the "Heavy Duty" shock as opposed to the "Comfort".

So between:

Bilstien
Boge (I don't think they are available in HD)
KYB

based on experince or what you've heard, which would you buy?

Oh, yeah, and any installation advice would really be appreciated, any special tools required?

Thanks much in advance!!!
