3 Link advice and opinions

[shmoov69]

Well, like the title says, I am looking for some GOOD advice on a set up for my 69. I have been wanting to put a 3 link in it for about 5-6 years now, but have not been able to let go of the car long enough to do it. My original plan was to copy a later model Camaro rear suspension. But now I see the kits that are being made and they make me wonder if the 3rd gen style would even work. I am not much into buying a kit (even if it is obviously far superior, and expensive!) if I can get something to work alot cheaper with the help of some friends.
I am wanting something that will work better than the leafs at the drag strip and still be able to rip corners. I know that a factory 3 link is not the best out there, but is it better than what I got? What are the drawbacks of copying a factory set up except with coil overs? using the front spring pockets for the lower control arm mounts and making some sort of torque arm to mount to the tranny cross member or something like that. I am no suspension guru, but don't know why it would not be better.
Please give me some feedback on this.
Thanks
