ignition help

[belldar]

Recently purchased a 72 c15 and have a key for the replacement door that was put on but the original ignition keys were lost and could not be found. I figure I will have to drill out my old ignition as I do not have a key to get the old one out unless some one has a really good suggestion for me!!! Where would you recommend getting a whole new ignition and door lock set from? I have found a couple places on line that have the kit for around the $30 range but just want to make sure I get a quality one or are they all the same? Got lucky with me 71 c10 super and it runs and drives great just needs some rust work, and now the 72 c15 is in even in better shape and I am praying it runs! ran when they parked it 6 years ago and lost the keys. I am into both now for under $500 together and may need help deciding when and what to do?!?! Will have to post up some picks later if I can find the time. Would really like to get an ignition and keys coming ASAP so I can see if the old girl runs. Hotwiring didn't go so well.
Thanks
