Is it only the kombi/caravelle bellhousings that are removable? if so, is the bolt pattern where it bolts to the box the same for all models?

It's the same bolt pattern for the Kombi 1600,1700, 1800 and 2ltr, don't know about the Caravelle

So can I bolt a type 1 motor to a kombi box ok?

the beetle box never had a removable bell housing?

the beetle never had a removable bellhousing.

To bolt a type 1 into a type 2 trans, you will need to put a type 1 input shaft in it (or cut a little off the type 2 one). This applies to gearboxes made for the type 4 engine.

Thanks Wes....the reason for the questions, is I have a renault 5sp box now, and found someone that makes adaptor plates to fit a vw bellhousing to the renault box.

however he didnt say what type of vw bellhousing. I'm hoping to use a caravelle one so I can use a hydraulic clutch.
