In last month's DOC article, I discussed the importance of finding and keeping the correct parts on our cars.  As the years go by, part numbers are being universally listed under a given car and year, instead of being specifically listed under car, year and series.  An example of a modern listing might be 1951 Chevy Radiator Cap:  '49-'51 All -- 4 lb. cap when actually the '49-'51 Chevys with a 216 manual shift used a non-pressure cap, and '49-'53's with a 235 Powerglide used the 4 lb caps.  Last month we listed vintage gas caps and this month we will list vintage radiator caps.

 

 
Hope this will help keep 'em running cool.  See you next month, and keep 'em driving!
