[Alfajay]

I believe the simple answer is "yes".

0ften when someone asks a question like this, they own a '69. And 1969 model Alfas were unique - your's has a hydraulic clutch with floor-mounted pedals, right? I've never seen a '69 bellhousing - does it have the slave cylinder retained by two snaprings, like the set-up used on hanging pedal cars?

If not, then you may need to install the '69 bellhousing onto the '72 transmission. I know that swapping bellhousings is necessary on pre-'69 (mechanical clutch) cars - I have a 115 gearbox in my '63 Giulia spider.

If your '69 box uses the "push down" style reverse lock-out, then you will need to retain the '72 gear lever, as the later boxes have a simpler system to prevent 5 --> Reverse shifts.
