Even though the FAM says, 1947-54 it is just meant to give you an over all idea of what
went where. A good portion of the illustrations are primarily aimed at the '54 model
years. You can't always tell if the same assembly ritual was followed for the earlier AD's.
All of the AD’s that appeared to be original that I've seen follow the fastener application
that we've been posting here. That is Clutch heads on the pre-54 models and slotted heads
on the post-54 cowl electrical units.
It would be very rare to find a 60-year-old vehicle that had the original VR anyway. Just
because the cover says Delco Remy doesn't mean that it is still the original VR. They did
make replacement parts also you know. Back in the day when I was working as a parts
man, the VR was one of the more common parts that was often replaced along with
rebuilt generators and starters, tires at 20k, points, plugs, cap & rotor at 8-10k.
We're so used to driving 80-100k without opening the hood or kicking the tires now days
that we forget that it took a heck of a lot more maintenance to keep these 50’s vintage
vehicles on the road.
