I just purchased an oil filter from Napa. the part # is 1100. This appears to be a perfect fit!! if anyone cares... smile.gif

I'll be makeing a note of it graemlins/hurray.gif After several tries I ended up just getting one from a Buick restoration supplier.

Is that the same as a '53 Special? I haven't had any luck finding one for mine.

Yes, that should be the same one. Your Special should have the straight 8 in it.
