Help!!! Buying 67 dart on saturday need front wheels..

If this car has the original 67 bolt pattern, you need a set of small bolt pattern wheels. They are 5 on 4". If this car has disk brakes in front I'm sure you will need at 14" wheels.
Look around for A-body wheels off any A-body from 61 to 72 and they should work.
Need a few more details to help you further.
