Which DIAL INDICATOR to order? (to match VW 2066 adapter)?

[epowell]

Hi...
I am about to embark on my first attempt at doing the INJECTOR PUMP TIMING on my 1.6 TD JX engine... I have located the DIAL INDICATOR ADAPTOR http://www.ebay.ca/itm/VW-2066-T3-T4-Au ... rmvSB=true" onclick="window.open(this.href);return false;

...but I have no idea what kind of DIAL INDICATOR I should order. I was told it just needs to be the right size as to couple with the ADAPTER 2066. Can anyone tell me what are the critical sizes I should be looking for? I am trying to source this dial indicator in the Czech republic and so far found a bunch with widely vary prices and various sizes --- here are a couple that I found (might these work?):
