What's different about a tubular UCA that provides this benefit? And does this also apply to a '68?
Tubular UCA's get rid of that stupid steel-on-steel upper control arm shaft with
screw in end caps, improve the motion ratio, fix the ball joint angle issue, vastly
improve the camber curve and are a helluva lot stronger. (some also add positive
caster as well) The elimination of squeaks alone (and the potential for squeaks)
is worth the price of admission.
The cars are the same from 65-73 with this suspension improvement. (65/66
have a unique upper shaft bolt pattern but all the rest on up are the same)
