401 replacement telescopic shock absorbers

[thanatoxic]

Bristoleers,

I'm seeking your advice & guidance on replacement front & rear telescopic
shock absorbers for the 401 I am restoring. I am replacing the "Bristol"
type front dampers (one is completely shot due to broken shock-pad) with the later arrangement including teles for which I now have the proper brackets etc. The rears were originally fitted with teles but are now just two
creaking tubes of rust!

Has anyone got the part numbers for the replacement Spax, Koni, or other
manufacturers equivalents for the original Newton (sometimes Newton &
Bennet) front & rear teles?

Any war-stories from those with experience on modern replacement teles would be most welcome.

Warm regards .......... Alan
