On the pedals, clutch and brake, there are little plastic bushes that make the pedals run true on the shaft, for less than a tenner it would be wise to at least have a look at these

The steering column bush is an almost service item to change do you may as well do that for te couple of quid it's going to cost

And the heater matrix, just had a look to make sure it's not leaking or bunged up, easy to swap with the dash out the way as its held in with 2 nuts and the screws on the bulkhead inside the engine bay
