I have been looking for a pair of shocks for the Rear of my 323i. I've come across a pair of Boge Sachs Gas Pressure Shocks. It says that it fits 76-83 320i's. My question, is that will it fit my 323i? I used to have Bilsteins w/ H&R's. Currently i have a pair of off-brand shocks off a 320i from a junkyard. Please let me know ASAP. Thanks!
