Went to a small local swapmeet Sat. and picked up a like new Schroeder cowl steering sector for 50 bucks. Guy said he didn't have a clue what it was but it had been hanging in his dads shop for about 30 years.
It may sound a little morbid but I buy all my sheetmetal from a casket factory. They have it in 16ga. & 19ga. I don't know they get their metal but it shapes and welds real good.
