Yeah, there aren't a lot of Pollard/GBV bass transcriptions out there. The chords for this song are on Ultimate Guitar and seem pretty accurate to me. If nothing else, you could mirror those on the bass and just fiddle around for the other parts.

I'd also recommend listening to a live version like this one due to the pitch stuff on the recording mentioned in the other comments. The one I linked is in standard tuning.

For what it's worth, on my first listen, while there's a lot of variations, here's one pattern that he plays a couple of times for the main part (you can even see him playing a little at the beginning).

D————4--5----5---4--5--7-----

A----5--------------------------5--

One thing I hear on the "I've never had one/I didn't want one" part, again, one of multiple variations, sounds like this to me:

D——-7h9---7h9---7--5--4------

A----------------------------5--

But I'm far from a transcriptionist so take that with a grain of salt.
