Modifying Steering Column??

[Mtrhd329]

Ok I have a few questions that I cant seem to find the answer to on here by searching....

I have a 79 c-10 and I am wanting to do two things to the column. First, I was wanting to upgrade the turn signal switch to the newer assembly with the lights switch, cruise contol, and wiper controls integrated into it. Is this possible?

Second I have converted to a stealth ignition system and there is no need for the ignition switch. Is there any way to swap in a turn signal housing piece(name?) That is from a pre 72 truck so I dont have the hole for the ignition switch anymore?

Basically I want to get rid of the ignition swtich and put a newer turn siganl arm in with all the goodies. Any one have any ideas?? No worry on the wiring as I am making my own harness for this truck.
