It was 4.6l in British Columbia, and 3.8l in Washington. So you had to convert dollars AND gallons to figure out gas prices.
I agree that SAE is a stupid, confusing system. To make the point it would actually make more sense if SAE did stand for "Standard American English." It actually stands for "Society of Automotive Engineers" from back in the early part of the 20th century when it developed standards for the US auto industry. SAE is now an international organization, and has used primarily metric units (SI) since the 1960s like everyone else. We still use the term SAE even though the measuring units are now more properly called United States Customary Units.
We were also told back when the US "rejected" the metric system in the 1970s that it was to save cost. Specifically the cost of retooling American car factories. It meant that every one who wanted to work on cars had to get two sets of tools, SAE and Metric. So, it certainly did not save *me* any money.
Dumbest of all is that we hang on to this stupid system although we have *not* actually rejected the metric system. All scientific measurements are metric. My metric tools sometime fit the nuts on my Dodge better than my SAE tools...which might be because it was made in Canada.
All that said, Fender, Gibson and a lot of YT continue to use inch-based measures...and as a result I use an analog ruler to do setup measures down to 64ths of an inch...which results in the need to do my conversions to mm with a calculator, hence my delay.
Glad that the shielding tape worked! It took me an embarrassing amount of time to realize how much easier that would be than dowelling and re-drilling.
