Something got into the fan. It comes out of the front of the blower housing directly in front of glove box. The under dash panel, knee bolster ribbed metal tube, and the glove box are removed to get to the screws. There are videos and instructions if you search. I found this complete one: https://ww...

That will not hurt. The disc will polish that area with use. Are the dowels and clutch cover bolt holes all in correct places?

That was a popular thing to do. The Daimler ownership of Chrysler led to some old Mercedes E class blueprints being used to make some currently produced FCA products as well as the Chrysler Crossfire being a warmed over one generation older SLK of that time.

The water pump is electric but it is uses a LIN controlled processor and has battery connected (unswitched) + and - connections. If anything killed the water pump it could have been low battery V from bad starter causing much higher current switching though the electronically commutated motor circui...

The fact it starts instantly pushed puts it squarely in the dirty trans and bell housing face or faulty starter territory. Starter current draw has been ruled out.
