430w documents to certify as IFR

[lithium366]

I purchased a used 430w and would like to install it and certify for IFR. As I am gathering all documents (I don't want to install at Garmin dealer) I have current STC and AML from FAA website, I also have a letter of permission to use the STC (found on the Internet but 400w installation manual from Garmin website also says they allow STC to be used by dealers, mechanics and owners). STC calls for Garmin400WSeries Master Drawing List, Drawing No.: 005-C0221-00, Rev. “B”. I can only find revision "A" on Garmin website. Does anyone have a revision "B" or later? The rest of the documents (AFSM and CI) are good
