These new seal kits are made from the correct EPDM material for use in RR363 cars.  Gallery seals are included.  
By default, this kit includes a 3/8"-24 bleed screw but many Silver Shadows have 10mm bleeders on the front calipers.  Leave a note in the comment section at checkout and I'll include metric bleeders.  If you don't know what you have and you don't want to go check, buy metric bleeders here just to be safe.
These seals and boots are a completely new design and they actually fit.  If you've struggled with seal kits from other vendors, you know how difficult some of these seals are to install.  
These kits are priced per caliper.  You will need 4 kits for the four front calipers.
