Looks allot like a couple I have. Believe it was made in 70 but not sure of all the coding at the moment - haven't studied that dating pattern yet but once we do I'll add it to the date coding article. Pattern changed over the years and goes back at least into the pre Mustang period. Have some others from around the same time as yours and 408 appears on others so the last four are likely the date code. In your example 1570. On a Motorcraft a couple of years later it shows 4082572
