I just completed the reseal of the 722.3 trans in my 1987 300D turbo. I also replaced the engine rear main seal. The new flywheel bolts I got from Mercedes Benz are different than what came out. The original bolts are 12-point 12mm. The new bolts are t50 torx. Are these upgraded bolts? Superseded part? What torque setting do I use? Is the locking plate from a newer model now required? Thanks in advance for your prompt/helpful reply. Hoping I have the right parts. Really need to get this all back together asap. I only want to do this job once, correctly.

You need to question mercedes about this . I had the same problem on the front disc replacment job that i did with hub to caliper
bolts .The ones i took out were shoulder bolts, ie not threaded right up to the head of the bolt . But new ones were threaded right up to the bolt head , and no support on the bolt as threads make it weak in that area. But i was told mercedes had superseded them .
