Thanks guys
Guess the toolshop will see me for the third day in a row.
Will get the 19mm socket with 3/4" drive and the longest breaker bar I can swing under the car. My toolkit is "growing up" at a pace now.
Will post a picture of my packed garage once the engine is out. All my new panels arrived today ( in smashed up boxes
), so I am glad to have an old BMW 730 on the drive for extra storage space.
