No it's not. This is a common error. The original bolt pattern on our cars is 5x4.5 like you said the new pattern is 5x115mm. enough imo to cause error.
It's like the neon wheels I bolted onto my 68 to roll it around on the stock 5x4"axle it's close but the short amount it's rolled has amounted to ruining the neon wheels for any other use because the holes are ovaled out like crazy now.
IMO redrill the axles and brakes for the wheels.
