84 Coupe DeVille lug pattern

I need to know what the lug pattern is for my car, cuzz i want to throw some new rims on it. also, would i need to lift it at all to put 22s on it?

It should be the 5x5 size, same as the full size chevy vans.
As for 22's, yes a lift is required, to give you the 4x4 look :-)

what would i need to do to lift the car, and could i do it myself pretty easy? would any wheel well modification be needed in the rear, because i have the sorta half skirted look on the quarterpanel.
