Have been re-doing this last night & this morning.
I had to use 3mm on the front lowers & about 1.5-2mm on the rear uppers.
The jigs & lengths of threaded bar are pretty essential, then check & again & again before tacking.
Was doing it last night late thought I had measured a million times, tacked it all up. On removal of the jig it was pretty obvious that the lower rears were out by about 5mmleft to right
.
All sorted this morning though
