Looks like there is a serial number break on the boom cylinder kits. I assume it is referring to the loader serial number.
Part Number 7J612-63400 is listed for loaders before 41590. I found that kit from 0ringsandmore for $27.30 plus shipping.
Part number 7J626-63400 for loaders built from 41591 on are $66.95 from Oringsandmore
The bucket seals also have the same serial number splits.
Serial number 41590 and before takes 7J612-64400. $27.75 at Oringsandmore.
Serial number 41591 and after take 7J629-64400. $29.75 at Oringsandmore.
