1y and AEF engines

Dear readers

i need to replace an Aef engine out of an skoda felica pick up only problem is that i live in the Netherlands and a good and cheap AEF engine is quite rare overhere.

so i started looking at other engines and the 1y engine looked almost exactly like the AEF engine (and we have plenty of those) but there are some diffrences like motormounts and dipstick.

My question is does a 1y engine fit if you screw on the motormounts and oil pan from an AEF engine or is it not an straight fit?

Thanks in advance
