"A type 4 engine (17,18,2000) will go onto a 1600 box no probs. gearboxes for type 4 engines have a slightly longer input shaft so a 1600 won't fit onto that."

there are people who'll say grind the shaft down, but i fell that's a bit of a waste and it's no big deal to remove bellhousing and change the shaft..

shaft goes further into Type 4 lump. but bell housings (1600s as well!) were seemingly all a bit longer after 75............. with a different (longer throw) starter motor too!
