what im sayin is,you have to make a new mark on a 210 flywheel,because the tdc mark on the 210 is not in the same spot as it was on the 200 mm,have fun doing a timing belt down the road,if you go by the orig tdc mark on the 210
when i converted to a 210,and i put the engine back in my car,i couldnt figure out why i couldnt get it timed right
i was scratchin my head for a few days,then i jammed some wire down the #1 injector hole to make a hillfolk piston stop,thats when i found the tdc mark was like an inch off,i re marked it,and everything was fine
it was a major pita too,being in the car with the trans installed
the next conversion to a 210 that i did,and i found that tdc mark not correct,but this time i was smart,i didnt have the trans back on yet and i made this tool
it worked great along with some half baked piston stop you can make to fit thru the prechamber hole
the one in the pic is for my tdi,but i used the tranny chunk though
