Sorry guys, wasn't sure where to post this but later In the year I want to do a full suspension and Bush strip down and rebuild, I figured a suitable impact wrench might help get rusty and tight bolts undone better than a spanner n hammer but after looking on line I'm left a little confused as they vary in so many different ways but I'm hopeful that there are a few decent mechanics on the Z forum who might be able to point me in the right direction please? Many thanks.
