e34 535i piston installation help

Ok so I've done lots of researching but cant seem to find any answers. I'm currently rebuilding my 89 535i. my issue is I cant seem to figure out which way the piston should be installed on the connecting rod. It can only go two ways but I don't want to install it the wrong way if it even matters. I understand the arrow on the top of the piston but does it matter which way the rod is? thanks for the help in advance!

Yes it matters. Sounds like you've probably gathered the arrow points toward the front main bearing, and the rods were directional on my V8. What's the last seven of your VIN? I'll see if I can come up with the info in TIS.

I am not coming up with the documentation on this. Sorry, expected to have responded earlier, but this is the first chance I've had. I take it you have no pictures of it coming apart either?
