I agree with you at a glance they look alike, but there is suttle differences between the two! Maybe there are part #s on the carrier that you could check with Detroit to verify model?Do you see any texture of the cast metal in any spots on the carrier around the bolts?I say this because if I remember correctly that was on my truetrac and not on my Detroit, it was all smooth.Sorry I could not be more informative,Good Luck!
