1st... 2nd... Oh I have no gears!!!

Looks like I wont be making Central day as I only have 2nd and Reverse!
Goes in 3rd, 4th, and 5th but nothing happens, 1st just makes a lovely crunching sound, and it rattles like a bag of spanners as i'm going along in 2nd

So.... what IB5 box (from what car and year please) fits straight on and will accept my Quaife ATB?
If anyone has one thats fairly low mileage let me know, I can have a courier collect if you dont mind bubble wrapping it up!

Thanks!
