Bill,

You've received good info on the F40/F41 suspension options. The F40 was included in the SS427/Z24 package. The F41 was optional...I have both on my '68 Z24 Sport Coupe (same styling as your '67). I installed Bilstein shocks all around about seven years ago...they're the best for my normal driving habits. Don't remember all the details when purchasing them. I think I had to determine a 'stroke' range before buying them.

I've included (3) pics of my rear axle area.
