John, I assume this is an early car, I'm on similar mileage to you and interestingly have done some of the same bits as you.
Couple of question for you.
How are you finding the simmonds steering wheel?
I have two spare front tubes, one has a centre value and the other an offset value, do you know what one is correct?
The under bonnet box looks interesting maybe you could post up the details for us all and some pictures of the car as well.
Oh and lastly welcome to TM
