So I went online to RockAuto last night and poked around on the site to see what service parts are for the likely repairs/maintenance I'd need to do to get it running. Most of them are ridiculously cheap. Even a brand-new gas tank is less than $100. As I've shared, longer-term, I'm going to pour five-figures worth of money into this project, but at least to get it running, registered, and smogged as-is, it's looking like it will probably be well less than $1,000. Can wait to get it going and take it to a few drive-in cruise nights!
