Would you happen to know where the vin number is located on them?
They are on a tab on the subframe. 9 out of 10 of them have broken off by now. It is farely rare for it to actually still be there.
86 & 87 has it on the left side, rear subframe, in front were the top of the chain pass, 88 & 89 is mounted on the frame between the two top front shocks mounts
