87 Iroc Hub Bore

I purchased a set of 02 camaro ss wheels for my Iroc. I know I have to run 2" spacers all the way around, but after searching for the hub bore, I geat alot of different answers. I have heard 70.3 for all third gens and also have heard 70.5 and 70.6 specifically for Iroc's. I dont want to run hub rings on the spacers I buy. Does anyone know for sure what the hub bore is for an Iroc? Its not that im too lazy to do the measuring, im just nowhere near my car. Thank's for the help!!
