Are the 64-65 B body seat frames the same?

[64SF]

I've recently purchased a 65 Satellite from a fellow member on the forum (thanks Coupe) and am looking at other seat cover options from the 64 model year rather than the 65.

The seat frames are the same for 63-65 B bodies, The A body seats are the same also! Will need the Bs tracks though!
