S13 strut brace fitting?

[PukkaSilvia]

Im going to buy one whatever as i know they can be made to fit but just fancied a bit more info. My old brace doesnt fit over my det so i need to get a new brace. I have been told the s13 ones need to be shortened to fit the s12 but the strutt mounts are in the correct place. Any further info? Is the adjustment bolt not enough on its own to get it the right length? If it needs to be cut etc it will need welding and re-chroming/polishing i assume. .
