Resto Roundup: Restoration Questions
Clutch Return Spring
I have a 1971 Mustang Boss 351 that needs a clutch return spring. I have looked everywhere for an N.O.S. or reproduction spring without any luck. Do you have a source for the correct one? Thank you!
Bill Upham at Mansfield Mustang has reproduced the ’71-’73 Mustang upper clutch return spring, which is PN D1ZZ-7523-A. This spring is correct for your Boss 351 as well. You can contact Bill via email at email@example.com or phone at (508) 339-5409. Mansfield Mustang’s website features an online catalog with many of its parts.
Shift Knob Quandary
What is the correct shift knob for a 1969 Mustang Boss 302? I see the woodgrain knob with white face and blue stripes, as well as the black knob with white shift pattern cut into it. Which is correct? Thanks!
Typically the C80Z-7513-F woodgrain knob with white face and blue stripes was used on cars with the optional deluxe interior. The C80Z-7213-A black knob was typically used on cars with the standard interior. I’ve provided a side-by-side photo of both here.
Engine Decal Location
I’m looking for information on location of the “246” decal on my 1966 Mustang with 289 K-code. I have seen this decal in multiple locations and would like to confirm its proper placement.

Typically, the engine ID decal is located on the coil for 1966. I’ve enclosed a couple of pictures for easy reference on proper decal location.
