What supports for intake swap

[ColonelMustard]

So I have a M52b28 OBD II swapped in the e30. The previous owner of the motor had done the OBD I intake manifold swap. However, it only has one support bracket bolted to the manifold, and there isn't another one.

Looking at realoem, they are different supports for OBDI vs OBD II. Do either version of the supports work? Does one set work better?

Also I currently have the crank case oil seperator and idle control valve just hanging out beneath the intake unsupported. Where are these supposed to mount to? Do they mount on the intake supports?

Found the answer.

"Bolt up two OBD-I manifold brackets to your block. Part numbers for the brackets are 11-61-1-735-265 and 11-61-1-738-759. Please note how the new brackets mount to different locations on the block. Front bracket mounts to a threaded hole in the block right behind the engine mount and the rear bracket mounts to an engine mount itself."

I ended up finding the answer myself by reading through a M50 mani swap DIY.

Do you need the brackets? Does it cause the intake to sag?
