ORIGINAL: 68/08 DroptopX2&lt\\;BR&gt\\;&lt\\;BR&gt\\;FYI &lt\\;BR&gt\\;Just keep in mind that the seller wants to sell. If you ask him &lt\\;B&gt\\;&quot\\;it will fit&quot\\;&lt\\;/B&gt\\; &lt\\;BR&gt\\;Get out the tap and you can always change out the driveshaft yoak&lt\\;BR&gt\\;&lt\\;BR&gt\\;Just a little more&amp\\;nbsp\\;to add&amp\\;nbsp\\;with Oxnard &lt\\;BR&gt\\;&lt\\;BR&gt\\;&lt\\;B&gt\\;Ford used the toploader in almost all production cars from 1964 to 1973. The transmission even ended up in some foreign cars.&lt\\;/B&gt\\;&lt\\;BR&gt\\;&lt\\;B&gt\\;A 1 1/16&quot\\; input shaft was used in motors from the 200 CID to the 390 CID. The larger motors such as the 427, 428 and 429 used a larger 1 3/8&quot\\; input shaft. The big block motors offered only close ratio gears in the toploader. The smaller engines offered both close ratio and wide ratio gears.&lt\\;/B&gt\\;&lt\\;BR&gt\\;&lt\\;B&gt\\;The gear box of the toploader came in three case lengths. The 1964 &amp\\;amp\\; 65 Fairlanes, the TVR, Griffiths and Sunbeam Tigers used a 25 1/2&quot\\; case. The 427 &amp\\;amp\\; 428 Cobras, all Mustangs, Falcons, Mavericks, Cougars, 1966 &amp\\;amp\\; 67 Fairlanes and Comets used a 24&quot\\; case. All full size Fords and the 428, 429 Cyclone and Torinos had a 27&quot\\; case. The 1964 toploader had a small 4 hole maincase with small OD bearing retainers. All the 1965-73 cases were wide 8 hole with larger OD bearing retainer.&lt\\;/B&gt\\;&lt\\;BR&gt\\;&lt\\;B&gt\\;The spline output shafts were also different. The 1964 and early 1965 25 spline output shafts proved to be defective and were quickly replaced. A 28 spline output shaft was used in cars from the 200 CID to the 390 CID. The big blocks had a 31 spline shaft. The toploader was used in 133 different models of Fords.&lt\\;/B&gt\\;&lt\\;BR&gt\\;
