Shock Absorber Disks

Does anyone know where to get shock absorber disks for a 1940 CP-65?

I have tried to Joe Rankin with no success.

Shock disks - When we rebuilt the aircraft about 20 years ago, I made new shock disks out of 1" thick rubber sheet bought from a local rubber stockist as the originals (then about 60 years old) were looking a bit ragged.  I cut them out with a jigsaw, as I didn't have a 4" diameter hole cutter, but that made them a bit untidy - no problem as they are covered up anyway. Last year I decided to tidy them up so took one in to a different rubber stockist.  He was able to supply me with 1" thick disks ready cut to 4" diameter, for about £1.50 ($2) each, bargain. I don't know what they would have been used for, probably some marine purpose I guess, but they fill the bill.  Not particularly resilient but as most of the shock absorbing is done by the tyres anyway, not a problem, they do squash up on compression and do the job OK. I'm sure a rubber stockist in your area would be able to help.

I can possibly help you out with the shock rubbers.
