I was just wondering if someone could help me with this. I know absoultely nothing about wheels except mine are no good. I was looking in the Jegs catelog and they had some 15x7 wheels that I could afford. But I don't know if they would fit on my car they give all this information

Rear Spacing: 4''
Bolt Circle: 5 x 4.5''

Rear Spacing: 4''
Bolt Circle: 5 x 4.75''

Rear Spacing: 4''
Bolt Circle: 5 x 5''

Rear Spacing: 4''
Bolt Circle: 5 x 5.5''

Rear Spacing: 4''
Bolt Circle: 6 x 5.5''

Would any of these sizes fit onto an 1985 Firebird. One other dumb question if these crager wheels have crager center caps, will my firebird center caps fit on to these they are crager 340 series

Thank You
