who makes them? are they good for driving or just show and when did they come out and fade away? wanted a set for my 65 389 engine with finned valve covers and a cross ram with period correct carbs and filters and make the engine bay that mid sixties custom look. any other cool 65 and later pontiac engine goody ideas?
Several places sell them. I bought mine from Vintage Ford in Sacramento. They work fine with my mallory dual point distributor. They are stiff when cold and flexible when warm. Mine have been on the car for three years and still look good.
here's some, brand new, very flexible: http://www.thehotrodcompany.com/shopnow/show_item.asp?product_id=spw%5Fclear25
