Master Cylinder help needed

Hi, a little help needed please…

Following an engine swap I'm looking to covert my mk1 to use the non-servo master cyclinder from an earlier model (which I've sourced) However, the shorter brake push-rod was not included with the cylinder so I left with having to make something to suit.

I was wondering if any body had one so I could have the dimensions etc. The part number is F 176 3000 001

Thanks in advance
