what physical difference in parts are the two options for belt drive conversion on shovelhead closed stock primary , electric and kick ?

1965-1984 belt kit... ( Vtwin 20-0625 )

1979-1984 belt kit... W/Rear belt drive ( Vtwin 20-0626 )

Bike is an 81 FXEF...but the gearbox has been changed out and not stock ,..so want to get the correct belt , pulley and hub

Thanks

The inner primary is different with OEM rear belt, clearance for the pulley. Not certain about mainshaft length.

All I got

something I learnt a few weeks back , the inner case is supposed to have slotted holes for 4 trans studs on belt models.
I personally have not seen this .
there could be difference in the starter motor housing to primary case . theres was prestolite then hitachi .
possibly the starter gear alignment with the ring gear ?

if you check out BDL indivual part numbers for basket for both kits and if its the same , then its all go .
main shaft didnt change till 1985 - 86 , so same M shaft from 1970 to 85 = 12.47"

Speculation only.... Perhaps the slotted inner primary was for the twin belt Sturgis models, short lived, only 3? Years. I've never seen a slotted inner.

I havent seen one , I cant imagine why it would need to be done if it was in fact done , and yes the only belt model would be sturgis .
theres 2 belts available BE and SE , seems to be some folk have trouble .
possibily after market cases are fractional longer ?
guys on HTT forum reakon they slot the holes but again it shouldnt be neccessary
