Goodyear Polyglas tires were first used and going forward in April of 1969. For Goodyear RWL fitments for vehicle build dates beginning in April 1969 through October 1969, use Goodyear Polyglas SKU# CB5KL. November through December of 1969, a running change was in place with Goodyear Polyglas installations. Thus either the CB5KL or CB5KJ may be used. As you can see, this encompasses the first half of the 1970 build year. Prior usage from 1967 through March of 1969 was the Goodyear Speedway Wide Tread series.
