Hub-centric wheels do not fit

I swear I have combed the forum before posting this so if i missed it don't beat me up too bad haha. I bought a set of wheelvintiques sbp rallye wheels off of a guy on Craigslist, he said he had them on a 1972 scamp. I have a 1971 scamp so I figured they would fit my car no problem, but when I went to put the front wheels on they did not fit the hubs! They are about a quarter inch or so from fitting flush, so my question is can I just use wheel spacers or do I have to have the center bored out? I live in the middle of nowhere and would definitely have to travel to have it done. Thanks
