This is a tip what ive used and works........
Use a B4 silver .71 front shock shaft

They are a lot stronger than the brittle gold shock shafts........
Dont fit the spacer under the piston, then wind the shock bottom on tight then back it off 2 threads to give you the same length as as B44 .80 shaft...............job done
