944 spring plates

[Brad_gt]

Hello ,
I have been lurking on the forums for a bit looking for some answers on a 944 rear suspension swap.
I got late model turbo alu arms , however the guy I got them from <junkyard> across the country torched off the spring plates .
I have not been able to find any 944 plates /torsion covers etc... locally
So I considering using swing axle plates/covers and bars .
My question does any one have a pattern to cut the spring plates , or a dimention to put the holes for the alu arms ?
Thanks
