Yea they can make them in 30 days but you can tell .....
OEM's have AAR approvals and quality checks that takes time before release.... We get parts from china and it takes up to 3 months of going back and fourth with tooling fixes before we can start shipping ..... Theirs all types of bad craftsmanship we try and resolve like sink marks and die pull marks and grain and gloss..
It's easy to remark on these thing unless you deal with this day after day and realize the difficulty involved
