Wheel Specification Check

I am looking to order a set of 17 inch torq thrusts for a 73 Duster and would like those that have been over this ground before to verify the model specs will be good to fit.

Front 17 x 7 - +0mm Offset and 4 inch Backspace
Rear 17 x 8 - +8mm Offset and 4.81 inch Backspace

If you think i have chosen incorrectly please throw me your comments. It's appreciated.
