1984, 300 L6, smogless, manual 3speed with overdrive.
Still investigating but pulled out of the fuel station and had a bang followed by conservative clunks coming from the underside. Limped to my shop got it off the ground and got quite a bit of play in the transfer case between the drive lines. It’s on stands and once a buddy gets here we’re going to run it in gear to narrow down the noise. Took a short video but I don’t use any of the host sites, if someone knows how to upload and is willing to upload one, shoot me a private message with an email and I’ll send it to ya.
