Dough Thorley Headers 79 T/A Olds 403 for sale

I have a pair of unused Doug Thorley header that ft a 79 TA with the olds 403

They been in my garage last 20 years, from a TA project but since we had a custom oil pan made the headers wouldn't fit. They are coated with a silver cermaic coating. I am in Arizona

If interested let me know I can send pics and such and discuss price. I cannot remember exactly what i paid I do remember they were expensive and the coating was like a couple hundred more or so

Also no idea what else they might fit other than they are for a Olds 403. These were ordered specific for the 79 T/A
