'78 Monte Carlo wheel help

[Geo's66]

Guys, just picked up a '78 factory 4-speed... Thinking sleeper look, painted Rally's black w Black paint. Question: thinking 17x8 rear, 16x8 fronts for a natural rake... Anyone have knowledge with these year g-body's on rims, back spacing and tire sizes? Thanks

for the 7", 3.75"bs-4"bs and the 8", 3.75"bs-4.25"bs depending on the tire width should work just fine
