This kit is perfect for those with automatics that are considering a future manual trans swap.  It has the sealed bearing shaft and adjustable clutch pedal stop provisions.  Just add my CK165-P cable kit later and you have everything!  (Makes it same as CK165-M)

(This conversion fits 1965-66 Mustangs with automatic transmissions. These kits will fit standard if you have cable or hydraulic clutch only)


Using this kit with a Toploader or T10 Transmission:

The quadrant kit is designed to be used with a T-5 or Tremec conversion and a cable clutch.  If you want to use the cable clutch
with an original Mustang standard transmission,  you will have to do a little fabrication.

In order to make the cable clutch work with the original type bellhousing, you must install a cable type release arm and a new
pivot bolt (fulcrum) in the bellhousing.  You will need a Mr. Gasket replacement fulcrum bolt and a Ford release arm from a 87-93
5.0 Mustang originally equipped with a T5.  You will need to have an aluminum plate welded into the bellhousing and then thread a
1/2″ hole in the plate for the new fulcrum bolt.  You will also need to fabricate a cable housing stop to go outside the bellhousing.
