Column & build sheet numbers???

[6pktgo]

I have 2 column collars that I`m trying to identify & I got a back seat that was suppose to be from a 69 satellite convertible?? ,but doesn't look right to me, but then I don`t know if there a difference from a hardtop seat? There was a small piece of the build sheet in it & readable were 9G 143127 ENG 925 FRONT BRAKE 25 & that`s about it? The column numbers are 2880 275 & 2880 075. Any body got any ideas? I can get some pics if that would help. Thanks

A rear convertible seat is "roughly" 1 foot narrower (shorter) than a hardtop seat.
