Compatible parts

Hello
I’m thinking about doing a Mk1 Auto to Manual swap.
Does anybody know if the Pedal Box (Clutch, Brake and Accelerator Pedals) from a 1.8 Mk2.5 fits the Mk1?
Also, I have a Starter Motor off the same 1.8 Mk2.5 (2002 year), would this be compatible with the 1.6 engine?
Or, does the Starter Motor need to be a 1.6?
Thanks
