I’m a newbie here but hope some of you might take the time to help.

It’s taken almost 10 years but I am almost done with my restoration of my non-sandcast KO. It was manufactured 12/69. Frame # 1015507

During a decade of securing rare parts (including brand new NOS Tach and Speedo!) I bought a used OEM non-duckbill KO seat and a nice duckbill seat cover thinking I would have the two mated when I was ready. Sent the both off to Sargent Cycle in FL to have it done only to find out that the older style seat cover did not fit the newer KO pan. They said the earlier pan was smaller and narrower and the older pan would not fit my bike.

If anybody is in the know I would love to have the answers and would be grateful:

1) Did my KO originally have the duckbill style seat?
2) Are the pans different?
3) If the earlier pan will fit my KO, are there any companies selling restored or remanufactured versions? Are any of them affordable to mere mortals?
