ok so i bought a set of 17x9 torque thrust type m's (black with machined lip) with 275-40-17 tires mounted and balanced that came off of a 97 trans am.. are these going to fit my 89 trans am?? what size spacers are needed? ive been looking but cant seem to find a positive answer, i think i need 2' for the front and back but im not sure..

wheel info taken off american racings site..
45 offset..backspacing is 6 3/4...and the bolt pattern is 5x4 3/4
