Porsche 924 rims on my first gen rx7?
 

There's a half off day at the wrecking yard and there's a Porsche 924 and I want to get the rims it has, I want to put them on my 1981 rx7, I believe the Porsche rims are 4×108 and my rx7 bolt pattern is 4×110, will the rims fit on my car, will I have to open the holes on the Porsche rims a little so they can fit properly, will the center section of the rims fit on my hubs, what do Vag com 15.7 have to watch out for and has anyone tried this already
