I've seen G85 F35's listed for $600 and I've seen open diff F35's listed for $1200. I posted mine (4.05 G85 with about that many miles) for $1000 and got a bunch of people telling me they were worth $400 or would I trade for a "dirt bike runs great just needs a spark plug just ain't got around to installing it", but someone ended up putting $960 in my hands for the trans plus my old intermediate shaft and half shafts. Took about 3-4 weeks of FB marketplace nonsense, but it did eventually sell.
