VW AWV Engine Swap into a MK1 Cabrio

Hey Everyone, I have read and searched but still a little confused.

I have a 92 Golf Cabriolet. I have removed a bad engine from it and purchased a donor car with a AWV 1.8T 20v engine in.

I have the original engine mountings on the mk1 but no bushes (body mountings not engine mountings). The original axles do not fit into the AWV gearbox. It seems the AWV axle holes are 100mm apart whereas my current mk1 axles are much smaller (I believe 90mm).

I am struggling to find a company that has this stuff in stock? Mountings are available but axles are not. Maybe flanges? Does anyone know where I can buy this from and if anything else is needed to get it swapped?

I have the complete beetle, key, cluster, immobiliser, transmission shifter etc but wish to use the original cluster.

Many thanks for all your help
