Project ready to start

Hi people
After a long search and with the worry of maybe getting made redundant i have had to put the mk1 project on the back burner.
but after finding out the job was safe and purchasing a mk3 2.0 16v gti over the week end i can now finally start it.

i am mainly just changing the engine but are there any other parts i can use off the mk3 which i would beable to use on the mk1?
cheers simon

Brakes?
