Spent the rest of the day detailing the engine bay and cleaning up the original booster. Used some cleaner and a brass brush to knock most of the surface rust off the front face. Next up will be the 309 master cylinder and the original lid. I also got this receipt emailed to me by George Kulp. He's the one that rebuilt the 302 back in 2015. I'd say he has a good memory as the parts are exactly as he described from memory when we spoke a couple of months ago. Nice of him to send me this copy of the receipt. I wish I could get a small block rebuilt for this kinda dough nowadays. (chuckling at that thought)
