I get my points from Steiner's New Parts for Old Tractors. They are all steel just like they used to be. One set has been on my 54 3100 for 3000 miles. Still look new. They fit "all Delco-Remy distributors with clip-on cap." Good quality. 5 and change +shipping.
Also have one of Jon G's condensers on.
