I have the Dallas Lankford Maintenance notes in PDF form.

I'll put them on MY site today.  I'm still swilling coffee, getting XYL 
to bed after a night shift, plus I have my 8 year old Granddaughter to 
run herd over since today is no school because of the Primary Election 
nonsens.

I'll post the link after I put it up on the site.
