Need help with coolant tank placement (M10) -> (M20) swap

[blackmamba1]

So I have a 1985 318i (M10) and I swapped in a 1987 M20B25

The 85 did not come with the mounting bracket for the tank. Right now I have it zip tied to the ac line. Its sitting really close to the headers so I would like to mount it some way.

I search but came up empty handed on this topic.

See picture below for current configuration.

I had this same question when i did the same swap... and no one around here answered then either.
So just my guess and i never had an issue but if you can manage, get the car level to set it up. the top of the radiator should be roughly the low fill level on the tank while cold. If the coolant were to drop below that line, then you'd have air in the system. I devised a custom bracket but no pictures atm.
