Modifications.
Steering wheel
The Steering wheel that the car came with when I bought is was a 12" Mountney leather wheel with a flat dish and this meant that the wheel ran very close to the dash, too close in fact, which meant that your knuckles would brush the switchgear for the indicators and high/low beam. Thankfully I had a nice old Mountney leather wheel with more dish and it was a slightly smaller diameter as well which gave nice bit of additional knee clearance as well.
Seat and seatbelt mountings
The seats had been changed from basic seat pads to steel framed seats that had runners on from a later wide body car. The trouble was that the runners raised the seats over an inch reducing the clearance from the wheel and worse the seatbelts were the wrong type for a Westfield and had eye bolts and quick release clamps for the lower fittings. Westfields should have bolt through fittings for the lower seat belt mountings so that the connection to the chassis is as flat as possible.
With the mountings changed and the seat runners removed the seat could be mounted as low as possible and moved back to sit flat against the rear bulkhead. And for the first time I could comfortably sit in the car.
