  * Starting July 1, 1973, there was a new design with a kick starter ratchet gear, bushing and spacer. The new 'pressed in' bushing has a Teflon coated lead bearing surface on a steel ball shell. The gear has a groove for the starter gear spring and the spacer length (and diameter) were increased to fit the new gear. ((HD Service Bulletin #618C as updated December 17, 1974))
  * The new ratchet gear assembly w / Teflon bushing was recommended for part replacement on all models built previous to July 1, 1973. However, these parts will not interchange with the old part numbers individually so the full replacement kit is recommended as an assembly. ((HD Service Bulletin #618C as updated December 17, 1974))

You can put a kick starter on a E1980 Sportster if it has a late production 79 motor. ((Hapster  of the XLFORUM)) \\
A kick start kit was available for parts order in the -80 parts catalog for 79-80 model XLs. ((1979-1980 HD Parts Catalog (99451-80) pg 29)) \\ The same kit was available in the -81 parts book but it was only sold for 1979 models. ((1979-1981 HD Parts Catalog (99451-81) pg 29)) \\
It's not clear if the same E79 parts were used in the kit or how far back it would retro but the 79-up parts books do not cover previous models. \\

Some early production 1980 models had the same plug hole and bushing for the kicker shaft as the 79 models had. ((Hapster  of the XLFORUM)) \\
We have confirmation of an early 1980 case with crankcase# (780 347 084), machined December 13, 1979 does have the hole for the kicker. ((OutlawTexan67 of the XLFORUM https://www.xlforum.net/forum/sportster-motorcycle-forum/sportster-motorcycle-era-specific-and-model-specific/ironhead-sportster-motorcycle-talk-1957-1985/28444-kicker-for-1980-ironhead/page3?t=47136&page=3)) \\
Some 1980 models came with a 1979 engine with 1980 numbers that match the H9 frame - (1979). \\
So it all depends on if you have a left over production 1979 engine installed. \\
