Hey all, would love to give you an update via pictures, but I've upgraded! Hope this doesn't break any rules, but I've started posting YouTube videos as I go along. Partly for updates, partly so other people can learn from things I've tried and failed at.
I'll keep posting on here for everyone but may link to videos also. Update is the install of a cross member with exhaust pass through.
