AH nice update on an old project! for some reason, your photo isnt showing of the car, be nice to see how it is now!
For projects, you can start a new project in the below section of the site specifically for Volvo projects:
https://www.volvoforums.org.uk/forumdisplay.php?f=45
Will be awesome to see updates on this.
On another note, have you sold off your PB brakes?! am looking for a big brake it badly. What sort ofr LSD are you looking for? im on that page as well and stuck between a gripper or a Quaiffe but really have no idea which one to go for yet.
