73 duster bbp. think I will go with the 17x6 4" bs with a 215 50. I'm looking at the weld laguna. Rears will be 17x8 4.5"bs with a 255 45

Nice! 17x6 with 4" BS should be good to go.
This is currently with 17x7 with 4.25" BS in the front and the rears are the same as what your planning 17x8 / 4.5 BS.
Tires currently are: Front 225/50R17 & Rear 255/50R17.
