Hey mate,
Yes, I am very happy with the rebels. You see heaps of minilites (with good reason) but these are pretty rare.
3.89 is what I went for in the end. It's just a 4 speed currently but I am on the look out for a celica 5 speed conversion if anyone has one floating around surplus to requirements.
I know you can use flywheel bolts to replace the crown wheel bolts which may have more clearance but there wasn't much material to remove anyway.
Cheers,
Matt
