Engine and frame ID help

Would that 1980 special II engine case work? i assume the special is just a cosmetic designation? my block number is 2L0 - 106053 a have discs front and back. rectangle taillights and my side covers say xs 400. i thought the special II's had special on the side covers but i may be wrong. i have no idea options package i have, but im pretty sure that its a xs400F based on yamaha motors online manual. any help?

Not found alot of information (this is an XS650 site after all )
But from what Ive found your motorcycle would appear to be either 1978 XS400E or a 1979 XS400F
As far as the 1980 crankcases are concerned, part numbers for 1978, 1979 & 1980 XS400 crankcase are all the same (1L9-15100-01-00)
Hope this helps a bit
