Happen to come across a large Mustang gathering last weekend, stopped in and talked to the various vendors about this spindle "problem".
Was very surprised to see brand new, early Mustang spindles with the small hole for the tie rod end.
Turns out that the 64-66 Mustang V-8 had small holes and the 63-65 Falcon V-8 had the larger diameter tapered holes for the tie rod ends.
Live and learn. |
