A very common part needing replacement on 1965 and 1966 Mustangs and GT350's with the 289 High Performance engines is the clutch equalizer bar. Sometimes this part is referred to as the "z bar". At any rate, originals are often bent, twisted, reinforced, repaired, and modified over the years. It is even interesting to note in
the Shelby American Automobile Club's Registry that there are many notes of these bars having been replaced on '65 and '66 GT350 Shelbys when they had just a few thousand miles.
Obviously, it is nearly impossible to find a good original. Even if you do find one that looks good, there is a very good chance that it is twisted.
We carry a reproduction from Scott Drake Mustang Parts that is absolutely super. Here, we have a few comparison photos of one of
our reproductions vs. an NOS bar. Please note that there are a few reproductions on the market. This one is by far the best. One of the others fit and functions just fine, but it just doesn't have the exact smooth bends that match the original.
Of course, you will notice the grease fitting in this reproduction. We recommend removing this and welding up the hole if you want it exactly like the original. Other than that, we would recommend this part on even the highest end restorations.
This bar has the block on the top like the '65 bar. This block can be removed to use on '66 Mustangs.
