Hello everyone. I'm about to embark on the passenger's seat for the first time (1989 CRG Automatic). I have two concerns. From outside the Van looking at the rear of the passenger's seat, I have a flat stud instead of a hex bolt, so I'm not sure how I'm supposed to get that off??? I will figure that part out, but my question is, am I to unscrew the top of my automatic shifting lever? Does that really unscrew? Doesn't seem like it would. Thanks.
