I wonder where Apex got that from, I’ve been searching and all I see is 10”.
I’m the same way about saving parts. My grandmother bought a ‘56 t-bird new and it was handed down to me. When I was building it, I saved ball joints, shocks, original fasteners, etc. just in case someone down the road needs them. When I built my wife’s 32 it was the same thing. I’d probably have room for another car if I got rid of saved parts.
