Side-by-Side Title/Registration

A few weeks ago, I posted a question here about buying a UTV from a guy who didn't have the title in his hand, but could get a new cert of origin from his dealer. Here's an update now...I still have a dilemma in getting registered/titled in my name though.

I bought the UTV from the original owner in LA, who bought it from a dealer in MS. The guy never got it titled when he bought it. He stuck it on his farm in MS, then brought it to LA a few months ago when he sold his farm. We wrote up a bill of sale and had it notarized.

He reached out to the dealer in MS that day and had them order a cert of origin. I just received that in the mail yesterday from the dealer. Here's my problem though, it has the dealer's name on the front as the distributor. On the back, they went ahead and signed on the dealer line and everything else is blank. I did not buy it originally from the dealership. I bought it from the guy who originally bought it, but his name is nowhere on the title.

What do I need to do here to get it registered in my name? I have the cert. of origin, I have the notarized bill of sale for my purchase, and I have the original invoice from the guy when he bought it at dealer. It feels like I'm kind of in purgatory here...like I need the cert of origin to first be recorded in the original owner's name, then transferred to me. Or, I need an invoice from the dealership for the sale in my name. Any other way?
