71 Cuda Rallye wheels

I have a 71 Cuda 340 4 speed that I will be restoring in the near future.It has been in storage for a long time,and pretty rough but complete.Checking the rallye rims today I find the date codes.Three are May 5 70 and one is May 4 70.The SPD is Feb 71.I know they built these cars with what they had,but do you think these wheels could be orig.to the car?
As always TIA

Yes

And the dates you have are quite common for original 390s
