    Push button bit overkill for a standard car, would destroy your gearbox over time,

    For all of us younger folk

    why the extended rod?
     
    If you have "excessive" clutch drag then the clutch is obviously being engaged slightly and having a extended rod could be the cause.
     
    Is the release bearing sitting correctly?
     
    Make sure all the parts you were supplied are correct also.
     
    Just to give you a idea of what a stock car may exhibit:- I currently have the rear end out of my E30 that has a Altezza engine and gearbox in it. Because the diff is not there to give some resistance the tailshaft will spin under the car if the engine is started in neutral. If you then hold the tailshaft as the diff would you do not get any drive. As the car warms up this goes away mostly also.

    My engine is not standard

    I compared the new clutch kit with the old, all ok.
    Thrust bearing - operated correctly before I bolted the G/box on.
     
    After attending and rectifying all possible causes, I came across the extended rod from twos r us, their ad states the following-
    ""People have found that aftermarket clutches, especially those with heavy pressure plates, make complete disengagement of the clutch difficult. This makes gear changes difficult and may make the transmission grind when shifting from neutral. ¼” longer than stock, made from CNC turned 303 stainless steel. This slightly longer shaft puts the slave cylinder piston further back in its bore, thus allowing a longer stroke and more disengagement.""
     
    sounds convincing.

    I would still remove it and see if your fault goes away. After all you did not have this issue before?
