Yes, and I may need to buy new, but they don't give any specs for bolt pattern. I was hoping someone had a pair they didn't need and could actually measure that so I know I'm getting the correct collector. These headers are 50 yrs old and bolt patterns may have changed over time. May need to call them and ask.

Ordered a set of Summit reducers as I needed 2.5 reduction and theirs stated inside diameter versus outside.
