1990's steering column in a 51

[abig84]

need some advice from people who have put a 80s or 90s column in one of these trucks which is the best way to go about it.

i gutted a 1991 silverado last year, using the engine, transmission steering column etc off it. i did save the bracket from under the dash but obviously isnt a bolt in. did you have to modify the column itself or the bracket?

im just worried about cutting a hole or doing something stupid where it doesnt work, after the column is in i think the rest of the build shouldnt be half bad. so any kinda tips or advice about whats the best way to tackle this project?
