But, if you have a '65 your clutch is not hydraulic, so the master won't do you any good.

Just used this kit the other day with good results.  Napa brake master kit # 387.

Will not seem right ie the parts seem too small but it will work, need to save some parts from yours.  The retainer clip is the main piece the one from the Napa is too small.  Also the Napa kit does not come with the piston spring so if yours is weak go with Riverpatrol's sugestion. 

I got great results with the Napa kit, followed by bench bleed, then new fluid and bleeding of all the brakes, just make sure all of you wheel cylinders are good.

This Napa kit was like $14 and a lot cheaper than the one on Ebay!
