XF 1.3 vBSEO3.8.x to xF NGINX rewrites

[Blackbeard]

Jake has been helping a bit...but we seem to have hit a wall.

The old urls with vBSEO were like this

http://www.domain.com/forums/taurus/146919-taurus-740-slim-showing-its-true-colors.html

(currently giving a 404)

However the new url looks like this
http://www.domain.com/threads/taurus-740-slim-showing-its-true-colors.146919/

So we are keeping the ID of the url.

Jake suggested to use

location ~* ^/forums/.+\.html$ {
rewrite [^/]+/([0-9]+)-[^\.]+\.html$
/threads/$1/ last;
}

or the htaccess to nginx converter suggested

rewrite ^/forums/[^/]+/([0-9]+)-[^.]+.html$ /threads/$1/ permanent;

The suggested htaccess that seemed to work for Jake previously was

RewriteEngine On

RewriteRule ^forums/[^/]+/([0-9]+)-[^\.]+\.html$ /threads/$1/ [R=301,L]

This doesn't quite work.

any help would be excellent.
I'm far from a nginx expert, or moderate. However, I can edit the conf and restart nginx pretty well.

Using rewrite rules is insane. A quick example of the proper way:
