HELP! What turbo do I need?!

Hello guys I have a 110 non pd golf, and I need a new turbo.
I’ve found a second hand AJM turbo which is apparently off a 110 but I think it’s off a 115, and my engine is a ASV, would this be a direct fit? it’s impossible to find straight answers as to what I can get for mine, is it a case of all the turbos being a direct fit other then the 130/150 turbos?
And to put a pd130 turbo do I just require the boost pipe to get it to fit?
Thanks in advance for any help

Get your original rebuilt, it should cost about £300 at the most.
