The recommended spark plug gap for a 1996 Harley Davidson 883 Sportster is .040. That is the most common gap for most Harley Davidson engines.
The suggested spark plug gap for a 1973 Harley Davidson is 0.040. It is the suggested gap for most of the spark plugs of that era.
the thickness of a paper matchbook works great
0.035 inch was a previous answer. I would seriously verify that. I show 0.035" as the SPARK GAP of the spark plugs, not the point gap inside the distributor. The point gap I found was more like 0.017" measured with the points open on the high lobe of the distributor shaft.
I believe it's 0.22" ( a matchbook or even a drivers licence is usually close enough )
