zenith tuner module 175-5073-01 compatability

[mr_fixer]

Hey All, i bought a NOS zenith tuner module 175-5073-01 off of fleabay, i'm hoping it will sub to a zenith chassis 23lc45z1 set that i own, which uses a 175-5074 which is in it, can anyone confirm or deny it as a replacement? i can do modifications if necessary. thanks Mike
