Does someone make a reverse (pull) spiral for 49-53 bars?

I am putting a cv carb on my 51 pan and I want to switch it to a pull throttle. The only reverse spirals I see avaiable are for 54 and up and are completely different than mine. They don't have the little retaining ring on them and the insides are different. Does some one make a reverse spriral that I can use with my bars? One that will match my spark side or do I have to fireplace both and the bars? I am A newbie so please shed some light on me. Thanks.

You need a spiral/grip sleeve for a H-D lightweight. You can source one from Taylor Classic Cycles. The lightweight throttles pull and match your left side.
