What style of sure grip is it? Clutch style or cone style. Id be intrested eather way so long as its "fix" able.

He said it came out of a 489 case. Assuming it's original it'd be a cone type. The only 489's that had a clutch type were real early 69's (first run that used left over clutch type sure grips)
