I am selling a slightly used hi performance steering box made by Flaming River.
This is advertised to fit 65 - 66 mustangs and early 1967. Could also work in a custom or hot rod application, it has a 1” splined sector shaft where the pitman steering arm attaches.
This has the quick 16:1 ratio , This originally came with a splined shaft , but is not included as shown in the fitting that is splined / splined/ in the first few pics , You can possibly purchase a splined shaft from them or use an aftermarket steering column.
Current retail after tax is over $900
I will sell for $475
for additional $25 I will include the U joint that has the correct splines on the box end and a "D" shaped other end for the column.
