The initial control arms were press cast. The cast had a SLIGHT imperfection in the pressing which in ONE extreme case lead to a hair fracture in a lower front control arm on a very early car .
To recast a modified or correct mold took to long as production was underway.
An outside contractor created BILLET ARMS front and rear with a COST to Ford of aprox $6,000 per set of 8 !
By the time to new cast was created and proven to be road worthy it wasn't till late 2005.
Aprox. to vin 1650 or so.....We took notes back in the day , I think one member had a vin 1675 or so still with the billet arms.
Its all in the original book …….which I don't have in front of me.
Remember if you see a 2005 vin 1600 or so and below with cast arms....either damage or ball joint issues .
Usually damage.
NO BILLET WERE REPRODUCED, Any factory warranty or accident work received the new pressed arms.....
In closing
SCOTT MINCH HAS A COUPLE FULL SETS LEFT.
Take out a mortgage but they are pure jewelry if you want it correct!
God luck!
