yep, exactly right old-tin.

but if you're sticking with the A series, a 60 series 5spd is fine for most worked NA engines as long as you don't abuse it. Or a patient search for a 63a box would be good for a turbo A series.

Having used and dsestroyed both 63 and 2T T50 boxes in different cars, I'd put money on the 63 being far stronger. It was behind more powerful L20 and L18 engines and raced for years before it broke. I busted a T50 with a less powerful 2TG road car that never saw the track.
