TOP SET T100 65-69
Piston ring top set for the T100, catalog years 1965-1969.
This is a piston ring top set listed for the T100 model years 1965 through 1969. "Top set" in the old parts-book language means the rings supplied for one piston - the compression and oil control rings that seal the piston in the bore. The catalog entry we have is brief, and we don't have more detail on it beyond the years and model it's tied to.

The JRC number is the modern reference form, with D820TRI as the alternate identity for the same part. If you're pulling a top end apart on a T100 from this era, this is the ring set to have on hand for that job.
Give us a call before you order if you want to double check bore size or ring specs against what's actually in your cylinder - we don't have dimensional detail on file for this one, so it's worth confirming fitment with the shop first.
