Depending on the purchase date of the AE shocks that were included in your Ellis kit, they might already be the 'bleeder' caps. Both my recent AE kits (B4 & B44) came with the 'bleeder' caps, but just needed the hole drilling and the addition of the small screw. I opt'd for the new Nor-Tech screws (originally marketed as hinge pin securing screws) link below.
