Default What could be causing this?

I have an 89 Bronco II with a 2.9L v-6, and the auto trans, it has gone through 2 flex plates now, so I picked it up off my friend to fix it and make it a trail rig He had the same thing happen and then replaced it with a junkyard flexplate and spacer. We pulled the engine and trans today and this is what we have came up with. No cracks in the bellhousing, I can not wiggle the crankshaft end with my hand nor can I do it to the input shaft of the transmission, the torque converter shaft is shaved up and so is the inspection cover, the flex plate is also ripped up. There are pictures down below.
So far I bought a brand new flexplate, it looks identical to that one, and a crankshaft spacer from the ford dealer, and brand new motor and transmission mounts, and am getting a new torque converter, what else could possibly be causing this?

I didn't see a plate between the trans and engine. Are you talking about a spacer between the bellhousing and the engine or between the bellhousing and trans? The only things that came off when I took it apart was some shavings from the inspection cover and the cover.

What do you mean by too much cow bell?...lol

should be a spacer/gasket just like that one in the pic with the starter hole, only at the top half of the engine, its a thick metal gasket just like the one in your pic. Maybe thats the problem. With it missing , it can make the engine and trans not mate together flat because you only have the bottom half of the spacer/gasket.

Yeah, I definately didn't take out a spacer, where could I get one at? Does anyone on here know anyone who has one?

Also I keep hearing about the front pump, what is that/where is that? is it part of the transmission or is it the torque converter?
Also could you give me a crash course on how to use the dial indicator, I am sure I can scrounge one up.

I found a guy on the ranger station forums who had one of these spacers that you are talking about, it goes around the whole bellhousing and at the bottom there is a door type thing that bolts shut so you can tighten the torque converter bolts. He said it looks like the one I have was from a manual transmission because you wouldn't need that door. What else should I replace to ensure that it quits breaking?
So far everything new includes flexplate, crankshaft spacer, motor/trans mounts, and a new spacer, I do not feel any kind of play in the crankshaft or transmission shaft, nor do I see any kind of crack in the bellhousing, is there anything else I should replace?
