1963 dart auto

anyone with someone info on 63 dart pushbuttom??? looks like I will need offset tranny crossmember mount insulator. does that insulator take a different bracket than the one where the insulator fits inside and is directly below where it screws to tranny ( that's what is on my 65 dart slant)???????
thanks for any info. I guess a 63 valiant would be same situation>??
i'm piecing back a roller.
