I pickup a older JDS Multi-Router. The Gas Spring/Strut is a little weak, part number and manufacture's name are not readable on the cartridge any longer. If you have a readable part number, could you post it here, or PM me with it. JDS wants almost $60.00 for it with shipping, and I see the same size one going for less then $20.00 on the WEB. Thanks for any help in advance. Tom
