I wasn't sure if it made sense to post here or in the Diesel section.

A condensed story: I've owned, driven, & maintained several old MB diesels. My "holy grail" has always been a diesel fintail. This past spring I moved to a new neighborhood & noticed a nice old '62 while out walking my dog. After months of drooling I noticed a for sale sign!
The owner & I have reached a fair agreement on price. It runs & drives & probably doesn't need to much to be my around town grocery getter/head turner.

I do most of my own mechanical work & have a manual on the way, but I'm having a heck of a time tracking down basic parts like spare drive belt, fuel filter, oil filter etc. Do I just have to go through the dealer for this stuff?
That's my main question, any leads would be great.
Also, the wipers aren't working which doesn't jive with rainy NW weather! Gotta get that fixed first.
Thanks,
MEK
