differences in T56 bell housings

[86LT1]

Ok, so im looking for a new bell housing for my camaro/firebird LT1 T56 tranny and as I search the web and ebay im coming across dodge viper T56 bell housings and GTO t56 bell housings and im wondering are these the same housings on all vehicles with the T56 or do I have to.specifically look for a camaro LT1 housing?Thanks

the housing,front plate and input shaft are different for all 3. they can be modified to work but it would be alot easier to just get an lt1 t56 unless you need the strength of the viper shafts.
