My name is Andrey...and I'm from Bulgaria. I have a lot motor hobby's (sport motorcycles then off-road jeep's then drift cars then...) and before a 2 mounts I bought an old BMW E21 315....the last madness

So I need some help...actually some dimensions.
I need exact distance between bolt who carries rear axle and center of wheel hub.
I have trouble to center my rear axle!
Thanx in advance!!!
