Can Anyone Identify These 15 x 7 Mopar Rallye Wheels?

[RSI700VIPER]

Recently bought a 1970 Challenger and it has 15x7 rims on it.   There is no part number by the valve stem, but the attached picture shows several identification marks.  On the back side of the rim, it says "15x7JJ", "Made in Canada", and some other numbers.  I did not remove the tire from the rim to see if there are any numbers there.  Are these repops?

Some of the early rally wheels did not have part no on them. 69 down wheels did not have part no. If they are early wheels, then they did not have part no. Not sure what month in 69 they started with part no. I bought a cuda and the rims were not original to the car but one of them has no part no. I forgot what month is was made in.. maybe June or July. Yours look like May 6 dated.

 Those appear to be Mopar performance"MP"  wheels from the '80s.

The no part number early ones are "made in USA" wheels

They're original. MP never made repo rally wheels.

I heard somewhere that the early 15 x 7 rallye wheels did not have part numbers.  I have a stack of 390 wheels but the part number is clearly visible by the valve stem.

In my opinion..the ridge where the valve stem is doesn't appear to be wide enough to be a 390 rim....just my first impression..

Can you post a pic of the stampings on the inside of the rim?

Could also just be the angle of the picture ?

I will try to get a picture of the inside of the rim tomorrow.  Inside meaning looking from the caliper, not with the tire off.

Here is a picture of the inside of the same rim.
