Help with 1964 Cherokee 180 for expanded cg envelope

[Srosenf137]

I am looking to buy a 64 Cherokee 180, S/N 28-1590. This predates the expanded CG envelope so I want to do the following per notes 8,9, and 15 of Type Certificat Data Sheet 2A13:

1. Operate in the utility category per Service Spares Letter 258,
2. Increase the aft baggage capacity per Service Spares Letter 242,
2. Expand cg envelope with landing gear strut p/n 65280-00 tube and AFM Support 2 (VB-261).

How and where can I obtain these parts and documentation? Are they still available? Will it be costly?

Many thanks for your help!

Steve
