I am finally getting around to lowering my car and have a couple questions. I have been looking at the site here and was wondering how many of each part on the top row I need. Also, what is the part number for the OEM strut mount? Do I need 4 or just 2? I have already bought the below items, the energy suspension set, and am going to purchase KYB dust boots.
(2)54034-31u01-front spring seat ("*SEAT-RU" on invoice
(6)54034-85e10-front urethane isolator ("SEAL-RUB" on invoice
(2)54329-39u00-front spacer ("SPACER-F" on invoice
(2)55034-31u00-rear spring seat ("*SEAT RU on invoice
(2)55031-33p10-rear urethane isolator("SEAL-RUB" on invoice
(2)55338-0m000-rear spacer (*SEAL-SH" on invoice
If there is anything else I left out please let me know. Thanks!

 

Are you talking about the strut bearing mount? If so, the OEM part number for both sides on the front suspension is 54325-31U01. Only 2 is needed, one for each side. I'm not sure for the rear suspension.
