K model vs Sportster forks

Hi guys, can anyone tell me when the switch to straight rather than stepped lower sliders took place? I have what appears to be an original early XLCH front end (embossed "XLCH" on lower clamp cover?), but it has the straight lower sliders which I had always thought to be K model. It's the one on the left in the pic below. Thanks!

Hi, Suicideshovel,

The stepped legs are 45944-68A: left, 45946-68A: right, so introduced on 68 XLH/XLCH.

They did not last long as they changed again in 70 by deleting the fender cast stays at the bottom.

Thanks Patrick! any ideas on the embossed XLCH lower clamp cover?

Sorry for the questions, and thanks for your help!

Hi Suicide Shovel,

Bottom tree chrome cover was introduced in 1964.

Thanks Patrick - I'm still missing a couple of the bridging parts manuals.
