Just my opinion,I would and have stayed away from wheel spacers.Definitly not a proper fix to the solution.When I went fro six to five lug wheels on the rear of my 55 I pulled the axles andtook them to Moser engineering in Indiana,they plugged and redrilled the hubs for five lug wheels. A little work and time involved but thety are done right.The front ones were done with an M2 kit from TCI,and they also work out good.
