Im going to fit the jack up linkage for rear shock from Rick Oliver, and need the c spanner to adjust the shock, can i use the spanner for the chain adjustment or can i improvise with screwdriver and hammer (carefully!)

And any important things to note whilst doing this mod?

Cheers,
Benny

get a proper tool - you know it makes sense.

Tyhe chain one is too big and a screwdiver will not work very well.

I bought one from my local shop for a fiver - made by progressive suspension.

I'll bet you can get an adjustable C panner for cheap enough from Halfrauds if you are stuck.
