need a little help
 

hello everyone, have a question for you all. i have a 75 oldsmobile cutlass supreme brougham, i just recently purchaced some factory rims for my olds. only problem is they dont all fit. the rims are 4 5/8 bolt pattern witch fits the front of my car, but the rear end has 4 3/4 bolt patern. come to find out the rear end is out of a 68 olds delta 88, its a 12 bolt posi and has stock 3.08 gears in it. my question is what should i do? should i change rear end out, or just axes, some one told me i should drill out the rims to fit. i really would like to put the factory rims back on. any help would be great, thanks.
