Bowser, backyard mechanic law says hobbyists always gain from their endeavors in ways few others can appreciate...... yet motorheads know each other on sight - speaking the same language and trading insights irregardless of whatever car they work on.

You've written the book on 450SE mechanical restoration!!

Git yer car on longhaul travel/trip and you can expect treatment as royalty wherever you go - comparing notes with other do-it-yourself mechanics.... and even putting others to shame with what you've done!

A/C work amounts to advanced degree stuff.... just keep flushing the system is what I've heard.
