JBA 1653 67 mustang 351W 4 speed top loader
I got a set of used JBA 1653 from ebay. So far I got the driver side header to fit. I had to clearence the header for the manual steering box; but it was pretty easy to do. These JBA 1653 3/8" flange headers appears to be very nice. I guess I'll throw my Headman 88650 headers away. The JBA 1653 clears Z bar nicely.
