944 rear arms

[SportyBug]

I know you get a lot of these but I am trying to make sure that I have the right stuff. I started to collect parts for a 994 brake conversion before college and had to put off working on my beetle to finish. I have a set of aluminum arms, spring plates and torsion bars that I believe are 86.5 NA.
Part #'s 951.331.513.0 (left) and 951.331.514.0 (right)

I have been looking to see if these are good arms to use as I cannot find them listed in the 944 part # article and searching I have not found evidence of anyone using them either
