JP,
The driveshaft won't lop off your balls; SPF's have driveshsaft loops!

I do raise my car on stands and check everything for tightness every time I change the
oil and grease the front suspension (3000mi) or whenever I have the car up for any other service. The only nuts on the whole car which have come loose are the Nylock nuts on the top bows. I replaced the bow screws with longer ones and used jam nuts to keep everything from coming apart. Other than that, I can't think of anything else coming loose on the car in almost 11K miles.
Hal,
I assume you meant a spare distributor, along with the spare alternator. Are you concerned about stripping a gear? Might it be worthwhile to fit a new gear, then just carry the gear and a pin? I've considered getting and perhaps even mounting a spare MSD box and carrying a spare stator or whatever the problematic part in the distributor is called. You could go quite a ways during the day with no alternator; at least to the nearest auto parts store in most parts of the country. I'm all in favor of carrying spare parts but space is at such a premium in these cars. I'm curious as to what other spare parts you carry but we can discuss the matter at SSR.
