The '97 was an odd year, there was both an AAZ with an 020 (cable clutch) and an AHU with an 02A (hydraulic clutch) depending what market you were in.
If you get a hold of the shifter parts for the transmission you have, it is a much better and stronger trans than the 020. It's also quite easy to do the swap in the Mk3 platform. The hole for the clutch master cylinder is already there in the firewall, the brake fluid reservoir already has the nipple for the tube to supply the master, the clutch pedal itself will work too as they used the same parts for both vehicles.
