ALL the axles themselves are the same (same casting number) and both the left and right spindles are identical for each of the earlies or each of the lates to each other also. The 61 to 63's with a longer king pin, and each bushing greased by a single zirc in each end of the spindle.The lates (64 to 67) have a zirc on each end that screws into a separate fitting that screws into the top and the bottom of the spindle. There are no over sized king pins available for the lates, however you can make an over sized (.010 over) out of an early pin, and cutting an additional groove into the early bushing to allow the grease to now enter through the late zircs. Like I said the spindles are the same from left to right, with the steering arms interchangeable. (if you can get them out?)LOL
Using the different height steering arms is a real good way of controlling the bump steer geometry, as the height of THAT ball joint is what directly affects bump steer. Pg 88 "HOW TO MAKE YOUR CAR HANDLE" HP BOOKS, BY Fred Puhn. EXCELLENT REFERENCE FOR DISC BRAKE FORMULAS AND HANDLING TIPS.

THE DUAL MASTER is ONLY available in 67 and not in 66. ONE YEAR ONLY. The same with the one year only matching offset brake pedal and matching eccentric bolt. Of which I have re sleeved and rebuilt.
