60-63 repair panel above w/s same as 64-66

[ls60apache]

hello all
ihave been working on some rust repair above w/s on my 60 I cut off a donor roof from a 65 a few years back from a pick n pull. and just recently bought the repair panel for a 60-63 that LMC and other parts suppliers sell.after cutting off the roof skin from the donor that I will be using on my 60, the above w/s section was in very good shape from the 65 donor so I carefully removed it and compared it to the lmc 60-63 panel. they looked identical to me, the bends around the w/s opening are a bit sharper than the repop. and it fits better where it meets the A pillar,so I will be using the original 65 panel on my 60. if you guys with a 64-66 need this repair panel then buy the 60-63 section I don't know why they list it only as for 60-63?
here are a few pics I had one showing the the fit at the A pillar with the repop but it got lost.
