Lou B - Great stuff! Keep up the good work!

I have purchased in recent weeks three of your guides (Vacuum Source, Diesel Performance, and 75MPH Guide) along with the valve adj. wrenches. Great stuff! Keep up the good work! Your manuals put the commonly available Chilton and Haynes stuff to shame. I have a 1979 300D I inherited from my Dad with less than 140K miles total and about 10K on a rebuilt engine but with various problems from having sat for awhile. Your guides give me the confidence to tackle the repairs! Thanks again!

Lou B.
