I have a set of front upper/ lower and spindles with poly's, painted black and looking very clean. They were from a project 3.1 that was parted out after the 2nd owner of the conversion gave up on it. So 0 km on them.
I am 45 min from decarie, 30min from the west island or 10 min from Grenville, depending on where you are driving from.
As for the coolant supports, I'll have to check under the car when I have time. Can't promise I'll have daylight to check before sat.
Call me if you have questions.
