LS motors have been installed. I'm going to attempt one soonish.
You will need motor mounts to place the engine in the right location . I believe people have used hooker headers (rear dump) to clear the steering box and you need a rear hump sump which Holley and others do.
I have heard that the gearbox fit can be an issue for some but not others so I'm not sure what to do there yet but I'm going to try a 4L60e.
If you have Facebook (Avanti swap page) there is a fellow selling his Ls swapped Avanti. Its rough looking but he might have some answers.

I thought it was around 12mm. I will check when I get home but it won’t be for a couple of weeks.

ps I’m trying to get some made up for my seats as well.
pps do you have the chrome pieces the hidem slots into ? That would be the width you need.
