You can get the adjustable push rod from most brake kit manufactures like SSBC and Master power. I think it is also in the NPD and/or Paddock catalog. I had that same delema with the push rod clip that would lock it into the MC if it was not right. I opted to assy my Master cyl with out that clip when I first did the conversion. That way I was able to make sure I had the right rod and set-up before locking it in. If the rod is the correct length and it is on the pedal correctly it won't pop out of the MC. Though the clip is a nice added saftey. As for getting it out of the MC once you put it in, I have a bad feeling you have to tear it down like you were going to rebuild it to get to that clip. On the first MC that was in my car, I put it in the bench vise and took a 1lb sledge to it and smashed it to bits to get that rod out, since I was throwing away the MC anyway. As for the correct unit to use, I used a Raybestos unit that was recogmended by Mustang Ranch in CA. You can also contact Trans Am racing for a recogmendation for the unit to use. He has a 15/16, 1", and 1 1/2" bore units for use with the Granada and/or Lincoln Versailles conversion.
