I run a CRT reverse manual VB. CRT recomennded installing the billet low/reverse servo piston because all his VB's are low band apply and I believe the A&A VB's are low band apply as well. YES YOU NEED IT. Yes you can install it with the trans in the car. I know I did it on mine. On a 904 you have to pull the tail housing off of the trans to access the hole to slide th epin out so the piston lever will drop far enough out of the way.....not hard just time consuming. I was also nervous about doing it but it's not a big deal. just a couple of bolts and a gasket. take off the DS and slide the tailhousing off of the output shaft, slide the reatining pin out and install the new servo and reinstall the piston lever and then bolt the tailshaft back up....piece of cake.
