Thanks for the comments, MrMack.
I got the boxes today, and will keep one together with the neat foot oil for adjusting the clutch leather when needed.
In the meantime I have had to change my driving plans with Solan as I got a heart attack a week ago, but luckily without any major damage. Nevertheless I have to leave the driving to Kari for some weeks, and as to the planned visit to Sweden we have to use our daily car and shorter travel.
Some future changes in eating and food, more training exercise and a lot of resting hours this first month will give me a good start after the incident.
Hope you all are enjoying the driving of your own old Chevys, and drive carefully as well! I am a little envious at the moment, but hope to get some travels with Solan/Petrine somewhat later in the autumn.
