THE NEW RELIANCE WITH SDS PROPS (GEN. 2 WITH PART # ENDING IN 20-00) DO NOT USE THE PREVIOUS SPECIAL DOG-BONE SHAPED SPACER WASHER (6CE-45997-00-00 .) THEY REQUIRE THE STANDARD SPACER 688-45997-01-00 AND CAN USE THE STANDARD PROP NUT KIT 6G5-W4599-00-00 SINCE THE GEN. 1 HUB USED THE SAME FLAT WASHER, NUT, AND COTTER PIN. (GEN. 1 SDS PROPS ENDED IN 00-00 OR 10-00.)
