This is a original TA Delete kit out of a early 1256 . It comes with the parts in the picture. The drive gears are are 20 degree so it will work in all 06 series 706,806,1206 and early 56 series 756,856,1256. Many aftermarket kits include the TA drive gear that acts as a spacer. Thie originals had a heavy duty snap ring on the counter shaft tube so the gear is not necessary. This also includes the pto drive gear which is in good condition.
