I did my own trans tunnel a while ago and it is no easy task. I'm more than happy with it tho. What material are you using there? Looks like .8?
Nice work on slotting the engine and box in
Chuck some decent plates on the gb mounts inside to spread the load out.
I know what its like doing work out of someone elses shop/shed thats ages away but keep chugging away mate...
Keep up the good work
