M5R1 issues
1991 2.3l Ranger, was going down the road hearing a slight metal on metal pinging when on the gas in 4th gear. Had a sleeve of sockets sitting on the tunnel so I moved them thinking that was the sound, about a mile down the road I’m coming to a stop and the clutch was rock solid. After trying to ease onto it the pedal went right to the floor. Clutch won’t do anything had to be pulled home. With the basic transmission knowledge I have I’d suspect it to be a hydraulic line. Or slave cylinder. I’ve never done any transmission work but I do believe everything on this transmission is internal. Any help would be greatly appreciated

Not sure what you mean by "rock solid" or "ease on to it". But the clutch control is hydraulic, with a slave cylinder mounted on the inside of the bellhousing and a master cylinder up on the firewall.
The metal pinging sound wouldn't be from the hydraulic system. It might be that the pressure plate locked up and you blew a seal in the master cylinder or slave cylinder when you tried to force it. If that's what ease on to it means.
The first thing you might do is to remove the rubber seal over the inspection port, underneath, and see if there are any pieces/clues in the bellhousing. Loose bolts, fluids, whatever.
Here's what the hydraulics look like.

Here's an image of an M5 R1. You can see the inspection port. You can peel the rubber plug out wuth your fingers.

Also, while on the subject, bleeding the clutch master to the clutch slave cylinder can be..."interesting", to say the least. I don't know if it's still available, but there used to be a YouTube video of some techs bleeding it by hanging it on the wall before installing.
I think some aftermarket kits have brake fluid already pre-filled to help with the bleeding. While you may or may not have clutch master and slave cylinder problems, you definitely want to replace everything while you have it apart, IMO.
