Some people use diesel oil because of higher levels of zddp.
Hot Rod magazine had a article on diesel oil in gas engines.
It said the zddp in diesel oil is for lower rpm engines and is different from the zddp in oils for gas engines that see higher rpms.
Use the right oil.

I couldn't find a local locksmith and gm dealers who could cut to the numbers on a 60 year old car.
I found a guy online from New Jersey who could cut to the numbers with original type key blanks . I don't remember the name.

When I got my '63, it had 5 keys that were copies of copies and didn't work very well. I had new keys made from the numbers.
The door skin can be removed to get the lock off to check the number and see if it matches the trunk.

I never have good luck getting those nuts loose with flare nut wrenches. I always end up using vice grips. The flare nut wrenches never fit snug .

Like Tom said your linkage can be adjusted so switch pitch can happen short off full throttle. I don't see any harm in using it.
I do try to let off the throttle when shifting from low to drive.

Front wheel drive and all wheel drive has made winter driving easier. Prior to this, weight in the trunk and snow tires were best way to go. People still forget how to drive till after the first storm.

The problem with some of those companies was that you were supposed to take your car back every year for inspection and most people didn't do that.
I worked with guy who had a 10 year old Ford pickup that looked like new. We figured his truck must have weighed 400 pounds more than the average with all the ziebart on it.
