interchangeable agitators
The Vari-Flex is interchangeable with the Roto-Swirl, Straight Vane, Roto-Flex, later Dual-Action and even a Whirlpool Surgilator as long as they are from standard cap. machines and have a splined shaft. There is a drive block adapter for the splined drive shaft you might still be able to find that will work with the older, mostly bakelite agitators like the "fat" Roto-Swirl, etc. Good luck and have fun - I always liked the many choices Kenmore had for agitation fun!
