Ares,
I created a spreadsheet with the parts I needed and wanted and priced them out and added 20% to cover miscellaneous plus $2000 for parts I didn't think of, can send you a sample just pm your e-mail address.
The to do list started before I got the car, cleaning, replacing, refurbishing Subaru donor parts, depowering the steering rack as an example. I requested the manual 6 months prior to chassis delivery and used it as a reference to start my assembly to do list. the build plan would always change some each build day. I my case it was due to changing something, needing supplies/waiting on parts or decision or just something I wanted to do differently.
