I did the same conversion on my '81. No problem but you need the original nuts and bolts for the alloy wheels. If you do not have them prepare yourself for a shock. They are about $10 each.

The nuts on the rear wheels seem like they do not catch enough of the thread. With the original nuts I don't think you need to change the lugs. Theoretically they could be about .5 of an inch longer. After that they would be too long (the nuts have caps) We (VW dealer and myself) looked at the original micro fisches but could not find any reference to longer lugs. Still, this question was asked before and responses were mixed.
