1981 t-top power window conversion

Will Daly

Any help would be greatly appreciated. Wondering if anyone has done this. I have a 81 manual window t-top that I am trying to convert with 89 power setup.
My doors have the triangle in the corner with the mirror mounted near “door pillar”

Installing the Motor assembly with door mounting plate (89) located the motor/gear drive into the inner window guide/ track. Is the window regulator different or are the brackets? I got the donor power stuff from a convertible too. Is that maybe the issue that the convertible window regulator is different? Lost/stuck!! Thanks!
