clutch

    I have a 74 620 pickup that has a 5 speed transmision.  I've been reading that this probably wasnt the original transmission since I believe in 74 the 620's only came out with a 4 spd.  My problem is this;

I replaced the clutch, pressure plate, throw-out bearing, clutch master cylinder and slave cylinder.  When removing the slave cylinder I noticed a past owner replaced the stock lenght rod (the rod from the slave cylinder that activates the fork) with a bolt about 1 and 1/2 inch longer than the original rod.  The original rod is too short.  I tried to use it and it work for about a day, then because it was so short it caused the internal piston on the slave cylinder to come completyly out, draining alll fluid and thus no clutch.  I have since re-installed the old bolt and it seems to work, but its hoky.

I would appreciate any knowledge or feedback on this.  I want to make it right.

More than likely you would need to know out of what vehicle the transmission came out of.  and replace the slave cylinder with that year.  easy way is to go to a auto parts store and try a few different z car  years.  or go to a place like rock auto and some times they give dimmetions as you pull up different years and such. or at least check the part #s for different years.

Thanks for the feedback.  I think your suggestion is the only way I can get the correct slave cylinder.  I looked at some parts stores on line for newer trucks but the part # was the same.  I had no idea the transmission could have come from a Z car.

Is there a way to identify what car my transmission came from?

Thanks for your help.

yea quite a few came from z cars they bolt right up. its just the prop shaft that has to be modified becasue they are longer.
