Harmonic damper fitment issues la360

I appreciate everyone's input and help with measurements, I found the issue to be the timing cover was a different depth than oem parts by roughly .250 so with some file work i got it worked down without cutting all the way through and I now have it seated, torqued and a little less than ⅛ of an inch clearance with full rotation, im sure it should probably be more but I dont want to blow it out and have to get it welded
