47-55.1 Steering column replacement advice

[vintovka]

Currently attempting to rebuild my worn out 78 chevy van steering column in my lifted 54. Its so bad the engine actually stalls if the wheel is lifted up!!!! Go figure that one.

Its got a 700-r4 tranny. If it fails any recommendations on a new one with Gm features like key, correct gear indicator, turn signals, horn, hazards and the like. There are so many out there its confusing. Without removing the column how do i tell what length it actually is.
