What to do with my 12 bolt?

[LSX69]

I need some help guys. I have a 12 bolt out of a 69 chevelle. It is stock length at 61.5" and I know a 69 camaro is 60". I really want to use this rear end since I already have it and I am not looking to spend any more money than i need to. I wanted to run a slightly more narrowed rear anyway so I would probably end up cutting up a 60" as well. My question is am I going to have any serious issues running this In my 69 camaro? What would you guys recommend doing? Any lengths you would say is best? The car is mini tubbed (DSE). Also any recommendations for rear end shops in the DFW area? Thanks for the help guys. -Jeff Loud
