ID questions, 15”x6”-5” backspace steely Mopar

[haywire 440]

I have a (4) set of these that show a Chrysler stamp, no #s. There is this dot 06 16 k26 t15x6-0 313.
The backspace is 5 1/4” . Offset is 3/8” (3/4” divided by 2).
Are these useful for any mini tubs, spring relocation or other modifications.
If not I was thinking of using them an a roller b-body, they are 1 1/2” away from the leaf springs.
Thanks, haywire

5 lug Dakota truck wheels. Backspace is wrong for a number of cars and trucks.
