Try any auto parts stores, most of them should have then, I got mine from NAPA auto stores, I think that they are a national chain. Also, try your public library, I was amazed, when I found a service manual for my 86 300SD benz at the library. If cant find one, e-mail me, and I can give you Haynes address, I dont have it handy right now, or I would give it to now hope this helps
