Front Suspension Upgrade...

I'm sure this has been covered many times but I just want to be sure I'm doing the right thing.

I have an 67 notchback barracuda with the five on four front-end. I just purchased what I believe to be the front suspension off a 73 scamp" Upper/lower control arms, spindles, all the disc brake stuff".

I just noticed yesterday the "73 scamp" lower control arms take a bigger torsion bar then 67 cuda.

So can i use the 67 barracuda lower control arms and torsion bars, 73 scamp upper control arms and spindles?? Then will there be any steering issues?? If this combonation works do I order 73 scamp upper control arm bushings and upper ball joint, then 67 cuda lower control arm bushings...

Does anybody sell a front-end kit with this swap already in mind??
Thanks for your help??
