Thanks ! appreciate that, saves me buying the wrong one and then finding all the geometry wrong.They're different.
172 PHASE 1 8200 195 989They are all the same, the only one that is different is a phase 1 subframe, every other subframe has the holes drilled further out than the phase 1 subframe.
I have had a pile of 7 subframes at one time, all from various sport models
172
172 cup
182
182 cup/cup packed
172 phase 1
The only one that is different is the phase 1 subframe, this is also backed up by part numbers and my own eyes.
