Check. I’m on the search for that.
You might want to find a guyt local who simply loves this kind of stuff who can guide you from there. Maybe run an ad on craigslist?
“Good shade tree mechanic wanted to help guide my resto project car. 1970 Buick Estate Wagon, 455. Need advice from someone honest and reasonable to look it over and reccomend what local shops can do what. Meet inpublic first time. $25/hr (somewhat negotiable), long term project . Maybe 15 hrs per week, +/-. Please have ready your backfeound info on what other cars from this erra you have worked on intensely. Email at first, need your phsone number, please, to weed out scammers. Put “I love Buicks” in the title so I know you are not spam.”
Along this lines. Don’t give phone number, just email, and be prepared for 10-1 spam replies, some quite clever.
Fwiw.
