Putting 20' x 9' rims on 83 cutlass supreme

[lbemedia]

A friend gave me some rims and i think that i will have some issues putting them on. They are universal and I'm thinking they will fit but i will need some low profile tires or will they rub The rims are 20' x 9' the back spacing is about 6' 1/2 - 7'. any help would be helpful thanks g- body forum.

Not with that backspacing. G bodies can only handle a 4.5bs with a stock set up.
