Hi, does anyone now a place to get the donut between the two manifolds( inside the center nut) or another one that will work, mine is loose when nut is bottomed out......

It's available from BMW, s/b less than US$25. Not sure you'd find it anywhere aftermarket, it's pretty low-demand item.

Thanks for p/n i looked in bmw epc and no option for 745 in e23 ,but i possibly didn't look hard enough. thanks again
