Sometimes I have to go to NAPA to get parts for my M35, but they are always expensive.

Autozone / Pep Boys / Advance Auto --- Those guys are great.... O'Reilly, has the accu-turn break lathe I like. Pep Boys has that old beater AMCO brake lathe, blah... they were good 60 years ago... when nothing better had been invented.

also tires.... i always call the tire places before I go out, and ask them if they have any like new sets(4) of used tires they want to sell me.

lotta times they will say no,,, or do not have anything in your size that is ok, you can call back a week later,

I will get a great set of 80 - 90% used tires installed for under 130 every time. ( Michelin / Goodyear / Pirelli )
